::JREN.BAT version 2.7 by Dave Benham
::
::  Release History:
::    2.7  2016-12-15: Added /NKEEP option.
::    2.6  2016-07-10: Fixed bug in ts() offset computations when the before and
::                     after have different timezones due to daylight savings.
::                     Added olm: and old: options to the ts() function to allow
::                     the addition of months/years without changing the local hour.
::                     In other words, the computation compensates for changes in
::                     dayling savings conditions.
::    2.4  2015-07-15: Added /?? and /??TS() paged help options
::    2.3  2015-03-03: Ignore invalid characters if /LIST mode
::                     Bug fix - abort if invalid character with /T mode
::    2.2  2014-12-10: Bug fix - forgot to make the search regex global
::    2.1  2014-12-10: Additional dt: options for FileSystemObject timestamps
::    2.0  2014-12-07: New /LIST option.
::                     Added ts() function and /?ts() documentation
::                     Many new JScript functions for use with /J with /LIST
::                     Added GOTO at top to improve startup performance
::    1.1  2014-12-02: Options may be prefaced with / or -
::                     Corrected some documentation
::    1.0  2014-11-30: Initial release

::============ Documentation ===========
:::
:::JREN  Search  Replace  [/Option  [Value]]...
:::JREN  /?[REGEX|REPLACE|VERSION|TS()]
:::JREN  /??[ts()]
:::
:::  Rename files in the current directory by performing a regular expression
:::  search/replace on the old file name to generate the new file name.
:::  This includes read only, hidden, and system files.
:::
:::  Search  - By default, this is a case sensitive JScript (ECMA) regular
:::            expression expressed as a string. The search is applied globally
:::            to the entire file name.
:::
:::            JScript regex syntax documentation is available at
:::            http://msdn.microsoft.com/en-us/library/ae5bf541(v=vs.80).aspx
:::
:::  Replace - By default, this is the string to be used as a replacement for
:::            each found search expression. Full support is provided for
:::            substituion patterns available to the JScript replace method.
:::
:::            For example, $& represents the portion of the source that matched
:::            the entire search pattern, $1 represents the first captured
:::            submatch, $2 the second captured submatch, etc. A $ literal
:::            can be escaped as $$.
:::
:::            An empty replacement string must be represented as "".
:::
:::            Replace substitution pattern syntax is fully documented at
:::            http://msdn.microsoft.com/en-US/library/efy6s3e6(v=vs.80).aspx
:::
:::  Options:  Behavior may be altered by appending one or more options.
:::  The option names are case insensitive, and may appear in any order
:::  after the Replace argument. Options may be prefaced with / or -
:::
:::      /D  - Rename Directories instead of files.
:::
:::      /FM FileOrFolderMask
:::
:::            Only rename files or folders that match any of the pattern(s)
:::            using standard wildcards. Multiple patterns are delimited by a
:::            pipe (|). Only complete name matches count.
:::
:::              * matches any 0 or more characters
:::              ? matches any 0 or 1 character except .
:::
:::      /FX FileOrFolderExclusion
:::
:::            Exclude files or folders that match any of the pattern(s)
:::            using standard wildcards. Multiple patterns are delimited by a
:::            pipe (|). Only complete name matches count.
:::
:::              * matches any 0 or more characters
:::              ? matches any 0 or 1 character except .
:::
:::      /I  - Ignore case when matching.
:::
:::      /J  - Treat Replace as a JScript expression.
:::            The following variables contain details about each match:
:::
:::              $0 = the substring that matched the Search
:::              $1 through $n = captured submatch strings
:::              $off = the offset where the match occurred
:::              $src = the original source string
:::
:::            The following are also available:
:::
:::              $n = An incrementing number for use in the name. The value
:::                   is reset to the /NBEG value for each directory.
:::                   It increases by the /NINC value for each renamed file.
:::                   The value may be zero padded to the width specified by
:::                   the /NPAD value.
:::
:::              lc(str)
:::
:::                 Convert str to lower case. Shorthand for str.toLowerCase().
:::
:::              uc(str)
:::
:::                 Convert str to upper case. Shorthand for str.toUpperCase().
:::
:::              lpad(string,pad)
:::
:::                 Used to left pad string str to a minimum length. If the
:::                 str already has length >= the pad string length, then no
:::                 change is made. Otherwise it left pads the value with the
:::                 characters of the pad string to the length of pad.
:::
:::                 Examples:
:::                    lpad(15,'0000')    returns "0015"
:::                    lpad(15,'    ')    returns "  15"
:::                    lpad(19011,'0000') returns "19011"
:::
:::              rpad(string,pad)
:::
:::                 Used to right pad the string to a minimum length. If the
:::                 str already has length >= the pad string length, then no
:::                 change is made. Otherwise it right pads the value with the
:::                 characters of the pad string to the length of pad.
:::
:::              ts( {option:value, option:value...} )
:::
:::                 Perform date/time computations and produce formatted
:::                 timestamps. This function can get the current date/and time,
:::                 or get the created/lastModified/lastAccessed timestamps for
:::                 the file being renamed, or parse a date/time from the name
:::                 of the file, or use a user specified value.
:::
:::                 Use JREN /?TS() to get help on the ts() function
:::
:::              attr( [offChar] )
:::
:::                 Lists the attributes of the file/folder. Set attributes are
:::                 listed in upper case and unset attributes are shown as the

:: =============== ts() documentation ===============
::+
::+ts( [ { [option:value [,option:value]...] } ] )
::+ 
::+  A JScript function that can performs date and time computations and return
::+  a formatted time string.
::+ 
::+  The option object argument within curly braces is optional - if no argument
::+  is given, then it returns the current timestamp using compressed ISO 8601
::+  format with milliseconds and local time zone - YYYYMMDDThhmmss.fff+zzzz
::+ 
::+    Examples:
::+      ts()  - Current date/time:  YYYYMMDDThhmmss.fff+zzzz
::+      ts({dt:'created',fmt:'{iso-dt}'})  - The file create date:  YYYY-MM-DD
::+      ts({od:-1,fmt:'{YYYY}_{MM}_{DD}'}) - Yesterday's date:  YYYY_MM_DD
::+ 
::+  Option names are case sensitive. There are 5 types of options:
::+    1) Specify the base date          - dt:
::+    2) Specify date/time offsets      - oy: om: od: oh: on: os: of:
::+    3) Specify the output time zone   - tz:
::+    4) Specify the output format      - fmt:
::+    5) Configure the day-of-week and  - wkd: weekday: mth: month:
::+       month names for non-English
::+       users
::+
::+  Specify the base date and time
::+
::+    dt:  Value specifies the base date and time. Many formats supported:
::+
::+      Current local date/time
::+        - do not specify a dt: value
::+        - undefined value
::+        - empty string ''
::+
::+        Examples:
::+          dt:''
::+          dt:undefined
::+
::+      Milliseconds since 1970-01-01 00:00:00 UTC
::+        - NumericExpression (math OK)
::+        - NumericString (no math)
::+
::+        Examples:
::+          dt: 1391230800000          = January 1, 19970 00:00:00 UTC
::+          dt: 1391230000000+800000   = January 1, 19970 00:00:00 UTC
::+          dt:'1391230800000'         = January 1, 19970 00:00:00 UTC
::+          dt:'1391230000000+800000'  = error
::+
::+      String timestamp representation
::+        - Any string accepted by the JScript Date.Parse() method.
::+            See http://msdn.microsoft.com/en-us/library/k4w173wk(v=vs.84).aspx
::+
::+        Examples: All of the following represent Midnight on January 4, 2013
::+                  assuming local time zone is U.S Eastern Standard Time (EST)
::+
::+          dt:'1-4-2013'                  Defaults to local time zone
::+          dt:'January 4, 2013 EST'       Explicit Eastern Std Time (US)
::+          dt:'2013/1/4 -05'              Explicit Eastern Std Time (US)
::+          dt:'Jan 3 2013 23: CST'        Central Standard Time (US)
::+          dt:'2013 3 Jan 9:00 pm -0800'  Pacific Standard Time (US)
::+          dt:'01/04/2013 05:00:00 UTC'   Universal Coordinated Time
::+          dt:'1/4/2013 05:30 +0530'      India Standard Time
::+
::+      File timestamps to millisecond accuracy using WMI. Very slow, but
::+      locale agnostic. WMI call may not work on some older machines.
::+        - 'created'   = Creation date/time of the file
::+        - 'modified'  = Last Modified date/time of the file
::+        - 'accessed'  = Last Accessed date/time of the file
::+
::+        Example:
::+          dt:'created'  = creation date/time of the file to be renamed
::+
::+      File timestamps to second accuracy using FileSystemObject. Very fast,
::+      but locale dependent. May not parse properly for some countries.
::+        - 'fsoCreated'  = Creation date/time of the file
::+        - 'fsoModified' = Last Modified date/time of the file
::+        - 'fsoAccessed' = Last Accessed date/time of the file
::+
::+      Array with 2 to 7 numeric expressions (local time only)
::+        - [year,months,days,hours,minutes,seconds,milliseconds]
::+            year and months are required, the rest are optional
::+            Missing values are assumed to be 0
::+            Missing values are not allowed between specified values
::+            month 0 = January
::+            day 1 = First day of month, day 0 = Last day of prior month
::+
::+          Examples:
::+            dt:[2014,3,1,17,30,22,457]  = April 1, 2014, 17:30:22.457
::+            dt:[2014,0,1]               = January 1, 2014, 00:00:00
::+            dt:[2014,0]                 = December 31, 2013, 00:00:00
::+            dt:[2014,,10]               = error
::+
::+  Date/Time offsets and time zone options all use the same syntax.
::+  The value represents a numeric offset for the specified time unit.
::+  It may be expressed as a numeric expression (math allowed), or
::+  a numeric string (no math allowed). Both positive and negative
::+  values may be used.
::+
::+    oy:  Year offset
::+    om:  Months offset
::+    od:  Days offset
::+    oh:  Hours offset
::+    on:  Minutes offset
::+    os:  Seconds offset
::+    of:  Milliseconds (Fractional seconds) offset
::+
::+    olm: LocalMonths offset (adjusted for changes in daylight savings)
::+    old: LocalDays offset (adjusted for changes in daylight savings)
::+
::+    tz:  Time zone used for output = minutes offset from UTC
::+
::+  The fmt: option is a string that specifies the format of the output.
::+  Strings within curly braces are replaced by dynamic components that are
::+  derived from the computed time stamp. Strings within braces that do not
::+  match a fmt: component are left as is. Strings not in braces are left
::+  as is. The format component names are not case senstive.
::+
::+  For example, a U.S. date would be represented as fmt:'{yyyy}/{mm}/{dd}'
::+
::+  The default format is '{ISOTS}', which yields YYYYMMDDThhmmss.fff+hhmm
::+
::+    {YYYY}  4 digit year, zero padded
::+
::+    {YY}    2 digit year, zero padded

Re: JREN.BAT - Rename files/folders using regular expression

#2 Post by dbenham » 30 Nov 2014 20:34

JREN.BAT is a hybrid JScript/batch utility that renames files or folders by performing a regular expression search and replace on the names. The utility is pure script that will run natively on any Windows machine from XP forward.

Use JREN /? to get help from the command line.

Important Note: It is a good idea to initially use the /T (test) option when developing a JREN command. This will print out the rename operations that would be attempted, without actually renaming anything.

Below are a few examples of usage. Often there are multiple ways to achieve the same result.

1) Convert all .txt files to lower case in the current directory:

Using the search regular expression and the /L (lower case) and /I (ignore case) options

Code: Select all

jren ".*\.txt$" "$&" /l /i

Using the search regular expression and the /J (JScript expression) and /I options

Code: Select all

jren ".*\.txt$" "lc($0)" /j /i

Using the /FM (file mask) and /L options

Code: Select all

jren "" "" /l /fm "*.txt"

Using the /RFM (regular expression file mask) and /L options

Code: Select all

jren "" "" /l /rfm "\.txt$"


2) Rename all 76 ".jpg" files in the "C:\photos\Christmas 2014" directory to an increasing padded number followed by a constant string. Assume the current directory is "C:\photos". Resulting file names should look like "01_Christmas2014.jpg", "02_Christmas2014.jpg", etc.

Using the search regular expression and the /P (root Path), /NPAD ($n pad width), /J, and /I options

Code: Select all

jren ".*\.jpg$" "$n+'_Christmas2014.jpg'" /p "Christmas 2014" /npad 2 /j /i

Using the /P, /NPAD, /J, and /FM options

Code: Select all

jren "^.*" "$n+'_Christmas2014.jpg'" /p "Christmas 2014" /fm "*.jpg" /npad 2 /j

Using the /P, /NPAD, /J, and /RFM options

Code: Select all

jren "^.*" "$n+'_Christmas2014.jpg'" /p "Christmas 2014" /rfm "\.jpg$" /npad 2 /j


3) Rename folders, moving a numeric suffix to the front of the name, padded to 2 digits. Recursively apply this only to folders with "test" as a parent folder, except ignore folders under the root path of "C:\someName\test". Assume the current directory is the root path where recursion starts.

starting folder hierarchy:

Code: Select all

C:\someName\test
              proj 1
                someName 1
                  cat 1
                  dog 2
                  zebra 3
                anotherName 2
                test
                  car 1
                  ignore
                  motorcycle 11
                  train 3
              proj 2
                test
                  eel 3
                  fish 2
                  turtle 1
              test
                baseball 1
                basketball 2
                football 3

desired result (default sort order swaps positions of folders)

Code: Select all

C:\someName\test
              proj 1
                someName 1
                  cat 1
                  dog 2
                  zebra 3
                anotherName 2
                test
                  01 car
                  03 train
                  11 motorcycle
                  ignore
              proj 2
                test
                  01 turtle
                  02 fish
                  03 eel
              test
                01 baseball
                02 basketball
                03 football

Using the /D (rename Directories), /S (recurse subdirectories), /PM (path mask), /PX (path exclusion), and /J options

Code: Select all

  jren "(.*) (\d+)$" "lpad($2,'00')+' '+$1" /j /d /s /pm "**\test" /px "/p:"

Using the /D, /S, /J and /RPM (regular expression Path Mask) options

Code: Select all

  jren "(.*) (\d+)$" "lpad($2,'00')+' '+$1" /j /d /s /rpm "c:\\somename\\test.*\\test$"


4) Hack to recursively iterate files or folders using sophisticated filtering

When JREN renames a file, it lists the original full path in quotes, followed by -->, followed by the new name in quotes. For example, using the example from 3), one line of output would look like:

Code: Select all

"C:\someName\test\test\baseball 1" --> "001 baseball"

It is fairly easy to add the /T option and process the result with FOR /F to selectively iterate files or folders. Using a Search that returns the entire name, and a Replace of "", coupled with the /T option, would yield results like:

Code: Select all

"C:\someName\test\test\baseball 1" --> ""

Then you just need to add FOR /F with the weird delims syntax to set the delimiter to a quote:

Code: Select all

  @echo off
  for /f delims^=^" %%F in (
    'jren ".* \d+$" "" /t /d /s /pm "/p:**\test"
  ) do echo %%F

yields:

Code: Select all

C:\someName\test\proj 1\test\car 1
C:\someName\test\proj 1\test\motorcycle 11
C:\someName\test\proj 1\test\train 3
C:\someName\test\proj 2\test\eel 3
C:\someName\test\proj 2\test\fish 2
C:\someName\test\proj 2\test\turtle 1
C:\someName\test\test\baseball 1
C:\someName\test\test\basketball 2
C:\someName\test\test\football 3

::
::************ Documentation ***********
:::
:::JREN  Search  Replace  [/Option  [Value]]...
:::JREN  /?[REGEX|REPLACE|VERSION]
:::
:::  Rename files in the current directory by performing a regular expression
:::  search/replace on the old file name to generate the new file name.
:::  This includes read only, hidden, and system files.
:::
:::  Search  - By default, this is a case sensitive JScript (ECMA) regular
:::            expression expressed as a string. The search is applied globally
:::            to the entire file name.
:::
:::            JScript regex syntax documentation is available at
:::            http://msdn.microsoft.com/en-us/library/ae5bf541(v=vs.80).aspx
:::
:::  Replace - By default, this is the string to be used as a replacement for
:::            each found search expression. Full support is provided for
:::            substituion patterns available to the JScript replace method.
:::
:::            For example, $& represents the portion of the source that matched
:::            the entire search pattern, $1 represents the first captured
:::            submatch, $2 the second captured submatch, etc. A $ literal
:::            can be escaped as $$.
:::
:::            An empty replacement string must be represented as "".
:::
:::            Replace substitution pattern syntax is fully documented at
:::            http://msdn.microsoft.com/en-US/library/efy6s3e6(v=vs.80).aspx
:::
:::  Options:  Behavior may be altered by appending one or more options.
:::  The option names are case insensitive, and may appear in any order
:::  after the Replace argument.
:::
:::      /D  - Rename Directories instead of files.
:::
:::      /I  - Ignore case when matching.
:::
:::      /FM FileOrFolderMask
:::
:::            Only rename files or folders that match any of the pattern(s)
:::            using standard wildcards. Multiple patterns are delimited by a
:::            pipe (|). Only complete name matches count.
:::
:::              * matches any 0 or more characters
:::              ? matches any 0 or 1 character except .
:::
:::      /FX FileOrFolderExclusion
:::
:::            Exclude files or folders that match any of the pattern(s)
:::            using standard wildcards. Multiple patterns are delimited by a
:::            pipe (|). Only complete name matches count.
:::
:::              * matches any 0 or more characters
:::              ? matches any 0 or 1 character except .
:::
:::      /J  - Treat Replace as a JScript expression.
:::            The following variables contain details about each match:
:::
:::              $0 = the substring that matched the Search
:::              $1 through $n = captured submatch strings
:::              $off = the offset where the match occurred
:::              $src = the original source string
:::
:::            The following are also available:
:::
:::              $n = An incrementing number for use in the name. The value
:::                   is reset to the /NBEG value for each directory.
:::                   It increases by the /NINC value for each renamed file.
:::                   The value may be zero padded to the width specified by
:::                   the /NPAD value.
:::
:::              lc(str)
:::
:::                 Convert str to lower case. Shorthand for str.toLowerCase().
:::
:::              uc(str)
:::
:::                 Convert str to upper case. Shorthand for str.toUpperCase().
:::
:::              lpad(string,pad)
:::
:::                 Used to left pad string str to a minimum length. If the
:::                 str already has length >= the pad string length, then no
:::                 change is made. Otherwise it left pads the value with the
:::                 characters of the pad string to the length of pad.
:::
:::                 Examples:
:::                    lpad(15,'0000')    returns "0015"
:::                    lpad(15,'    ')    returns "  15"
:::                    lpad(19011,'0000') returns "19011"
:::
:::              rpad(string,pad)
:::
:::                 Used to right pad string str to a minimum length. If the
:::                 str already has length >= the pad string length, then no
:::                 change is made. Otherwise it right pads the value with the
:::                 characters of the pad string to the length of pad.
:::
:::      /L  - Convert names to Lower case. Entire names can be converted to
:::            lower case without any other changes by using empty strings ("")
:::            for both Search and Replace.
:::
:::      /NBEG BeginValue
:::
:::            Specifies the initial $n value for each directory. The value
:::            must be an integer >= 0. The default value is 1.
:::
:::      /NINC IncrementValue
:::
:::            Specifies the amount $n is incremented after each rename.
:::            The value must be an integer >=1. The default value is 1.
:::
:::      /NPAD MinWidth
:::
:::            Specifies the minimum width for each $n value. If the $n value
:::            has fewer digits than MinWidth, then the value is zero padded
:::            on the left to achieve the MinWidth. The value must be >= 1.
:::            The default value is 3.
:::
:::      /P RootPath
:::
:::            Specifies the path where the rename is to take place.
:::            The default of . represents the current directory.
:::            Wildcards are not allowed.
:::
:::      /PM PathMask
:::
:::            Only rename files or folders whose parent folder path matches
:::            any of the PathMask pattern(s) using augmented wildcards.

I am going to suggest to JJ Abrams that we name the new Star Wars movie: Star Wars Episode VII: Jscript Awakens. :lol:

Minor release:
- fix some documentation
- Allow options as -Option or /Option

JREN.BAT Version 1.1

Code: Select all

@if (@X)==(@Y) @end /* Harmless hybrid line that begins a JScript comment
::JREN.BAT version 1.1
::
::  Release History:
::    1.1  2014-12-02: Options may be prefaced with / or -
::                     Corrected some documentation
::    1.0  2014-11-30: Initial release
::
::************ Documentation ***********
:::
:::JREN  Search  Replace  [/Option  [Value]]...
:::JREN  /?[REGEX|REPLACE|VERSION]
:::
:::  Rename files in the current directory by performing a regular expression
:::  search/replace on the old file name to generate the new file name.
:::  This includes read only, hidden, and system files.
:::
:::  Search  - By default, this is a case sensitive JScript (ECMA) regular
:::            expression expressed as a string. The search is applied globally
:::            to the entire file name.
:::
:::            JScript regex syntax documentation is available at
:::            http://msdn.microsoft.com/en-us/library/ae5bf541(v=vs.80).aspx
:::
:::  Replace - By default, this is the string to be used as a replacement for
:::            each found search expression. Full support is provided for
:::            substituion patterns available to the JScript replace method.
:::
:::            For example, $& represents the portion of the source that matched
:::            the entire search pattern, $1 represents the first captured
:::            submatch, $2 the second captured submatch, etc. A $ literal
:::            can be escaped as $$.
:::
:::            An empty replacement string must be represented as "".
:::
:::            Replace substitution pattern syntax is fully documented at
:::            http://msdn.microsoft.com/en-US/library/efy6s3e6(v=vs.80).aspx
:::
:::  Options:  Behavior may be altered by appending one or more options.
:::  The option names are case insensitive, and may appear in any order
:::  after the Replace argument. Options may be prefaced with / or -
:::
:::      /D  - Rename Directories instead of files.
:::
:::      /I  - Ignore case when matching.
:::
:::      /FM FileOrFolderMask
:::
:::            Only rename files or folders that match any of the pattern(s)
:::            using standard wildcards. Multiple patterns are delimited by a
:::            pipe (|). Only complete name matches count.
:::
:::              * matches any 0 or more characters
:::              ? matches any 0 or 1 character except .
:::
:::      /FX FileOrFolderExclusion
:::
:::            Exclude files or folders that match any of the pattern(s)
:::            using standard wildcards. Multiple patterns are delimited by a
:::            pipe (|). Only complete name matches count.
:::
:::              * matches any 0 or more characters
:::              ? matches any 0 or 1 character except .
:::
:::      /J  - Treat Replace as a JScript expression.
:::            The following variables contain details about each match:
:::
:::              $0 = the substring that matched the Search
:::              $1 through $n = captured submatch strings
:::              $off = the offset where the match occurred
:::              $src = the original source string
:::
:::            The following are also available:
:::
:::              $n = An incrementing number for use in the name. The value
:::                   is reset to the /NBEG value for each directory.
:::                   It increases by the /NINC value for each renamed file.
:::                   The value may be zero padded to the width specified by
:::                   the /NPAD value.
:::
:::              lc(str)
:::
:::                 Convert str to lower case. Shorthand for str.toLowerCase().
:::
:::              uc(str)
:::
:::                 Convert str to upper case. Shorthand for str.toUpperCase().
:::
:::              lpad(string,pad)
:::
:::                 Used to left pad string str to a minimum length. If the
:::                 str already has length >= the pad string length, then no
:::                 change is made. Otherwise it left pads the value with the
:::                 characters of the pad string to the length of pad.
:::
:::                 Examples:
:::                    lpad(15,'0000')    returns "0015"
:::                    lpad(15,'    ')    returns "  15"
:::                    lpad(19011,'0000') returns "19011"
:::
:::              rpad(string,pad)
:::
:::                 Used to right pad string str to a minimum length. If the
:::                 str already has length >= the pad string length, then no
:::                 change is made. Otherwise it right pads the value with the
:::                 characters of the pad string to the length of pad.
:::
:::      /L  - Convert names to Lower case. Entire names can be converted to
:::            lower case without any other changes by using empty strings ("")
:::            for both Search and Replace.
:::
:::      /NBEG BeginValue
:::
:::            Specifies the initial $n value for each directory. The value
:::            must be an integer >= 0. The default value is 1.
:::
:::      /NINC IncrementValue
:::
:::            Specifies the amount $n is incremented after each rename.
:::            The value must be an integer >=1. The default value is 1.
:::
:::      /NPAD MinWidth
:::
:::            Specifies the minimum width for each $n value. If the $n value
:::            has fewer digits than MinWidth, then the value is zero padded
:::            on the left to achieve the MinWidth. The value must be >= 1.
:::            The default value is 3.
:::
:::      /P RootPath
:::
:::            Specifies the path where the rename is to take place.
:::            The default of . represents the current directory.
:::            Wildcards are not allowed.
:::
:::      /PM PathMask
:::
:::            Only rename files or folders whose parent folder path matches
:::            any of the PathMask pattern(s) using augmented wildcards.
:::            Multiple patterns are delimited by a pipe (|). Only full path
:::            matches count.
:::
:::              /P:  matches the root path specified by option /P
:::              **   matches any 0 or more characters
:::              *    matches any 0 or more characters except \
:::              ?    matches any 0 or 1 character except . or \
:::
:::           This option is only useful if the /S option is used.
:::
:::      /PX PathExclusion
:::
:::            Exclude files or folders whose parent folder path matches any

Re: JREN.BAT - Rename files/folders using regular expression

#7 Post by dbenham » 07 Dec 2014 17:16

Here are the new version 2 features:

1) Added ts( [ { [option:value [,option:value]...] } ] )

JScript function for use with /J option that performs date/time computations and returns a formatted timestamp string. I basically adapted the code from my getTimestamp.bat utility. Base dates can be derived from many sources:

- Parsed from the file/folder name
- Any of the file/folder timestamps: created, last modified, last accessed
- Today's date
- Any date of your choosing, with many options for input format

The ts() function has so many options, it needs its own dedicated help section :!:
There is a new help option to get ts() help:

Code: Select all

JREN /?TS()

2) Added the /LIST option

Display the Replace result only, without quotes, and without renaming anything.
Useful for producing user formatted directory like listings.

3) Added the following JScript functions for use with /LIST coupled with /J

File/folder attributes with optional left padding:

Code: Select all

size( [pad] )    - Size of file, or size of folder including subfolderrs

File/folder attributes with optional right padding:

Code: Select all

 attr( [pad] )    - List of characters representing attributes: RHSALC
 type( [pad] )    - A description of what Windows thinks the file is
 name( [pad] )    - The name
 path( [pad] )    - Full path
 parent( [pad] )  - Full path of the parent folder
 sName( [pad] )   - Short 8.3 name
 sPath( [pad] )   - Full path using short 8.3 names
 sParent( [pad] ) - Full path of the parent folder using short 8.3 names

4) Put a GOTO at the top to improve startup performance.

It took time for the batch processor to parse the extensive documentation, even though it does not get executed. The GOTO at the top skips the documentation, so startup times are noticeably faster.


Usage Examples:

Put the file creation timestamp at the beginning of all .txt file names

Code: Select all

C:\test>jren "^" "ts({dt:'created',fmt:'{isots} '})" /j /fm *.txt
"C:\test\a+b.txt"  -->  "20141130T121529.565-0500 a+b.txt"
"C:\test\jrepl.txt"  -->  "20141114T082855.961-0500 jrepl.txt"
"C:\test\lib1.txt"  -->  "20141125T195220.565-0500 lib1.txt"
"C:\test\lib2.txt"  -->  "20141125T195248.845-0500 lib2.txt"
"C:\test\new.txt"  -->  "20141119T233717.484-0500 new.txt"
"C:\test\old.txt"  -->  "20141119T233614.131-0500 old.txt"
"C:\test\out.txt"  -->  "20141108T162720.521-0500 out.txt"
"C:\test\test'it'.txt"  -->  "20141126T140119.044-0500 test'it'.txt"
"C:\test\test(it).txt"  -->  "20141126T144219.394-0500 test(it).txt"
"C:\test\test,it.txt"  -->  "20141126T135759.083-0500 test,it.txt"
"C:\test\test.txt"  -->  "20141112T084515.880-0500 test.txt"
"C:\test\test2.txt"  -->  "20141114T173346.175-0500 test2.txt"
The ISO format is great because it sorts chronologically, except for timestamps around the transition to or from daylight savings time. The timestamps always sort chronologically if you use UTC timestamps:

Code: Select all

C:\test>jren "^" "ts({dt:'created',fmt:'{isodt}T{isotm}Z ',tz:0})" /j /fm *.txt
"C:\test\a+b.txt"  -->  "20141130T171529.565Z a+b.txt"
"C:\test\jrepl.txt"  -->  "20141114T132855.961Z jrepl.txt"
"C:\test\lib1.txt"  -->  "20141126T005220.565Z lib1.txt"
"C:\test\lib2.txt"  -->  "20141126T005248.845Z lib2.txt"
"C:\test\new.txt"  -->  "20141120T043717.484Z new.txt"
"C:\test\old.txt"  -->  "20141120T043614.131Z old.txt"
"C:\test\out.txt"  -->  "20141108T212720.521Z out.txt"
"C:\test\test'it'.txt"  -->  "20141126T190119.044Z test'it'.txt"
"C:\test\test(it).txt"  -->  "20141126T194219.394Z test(it).txt"
"C:\test\test,it.txt"  -->  "20141126T185759.083Z test,it.txt"
"C:\test\test.txt"  -->  "20141112T134515.880Z test.txt"
"C:\test\test2.txt"  -->  "20141114T223346.175Z test2.txt"

Add yesterday's date to the end of each file name, immediately before the extension:

Code: Select all

C:\test>jren "(\.txt)$" "' '+ts({od:-1,fmt:'{iso-dt}'})+$1" /j /fm *.txt
"C:\test\a+b.txt"  -->  "a+b 2014-12-06.txt"

::============ Documentation ===========
:::
:::JREN  Search  Replace  [/Option  [Value]]...
:::JREN  /?[REGEX|REPLACE|VERSION|TS()]
:::
:::  Rename files in the current directory by performing a regular expression
:::  search/replace on the old file name to generate the new file name.
:::  This includes read only, hidden, and system files.
:::
:::  Search  - By default, this is a case sensitive JScript (ECMA) regular
:::            expression expressed as a string. The search is applied globally
:::            to the entire file name.
:::
:::            JScript regex syntax documentation is available at
:::            http://msdn.microsoft.com/en-us/library/ae5bf541(v=vs.80).aspx
:::
:::  Replace - By default, this is the string to be used as a replacement for
:::            each found search expression. Full support is provided for
:::            substituion patterns available to the JScript replace method.
:::
:::            For example, $& represents the portion of the source that matched
:::            the entire search pattern, $1 represents the first captured
:::            submatch, $2 the second captured submatch, etc. A $ literal
:::            can be escaped as $$.
:::
:::            An empty replacement string must be represented as "".
:::
:::            Replace substitution pattern syntax is fully documented at
:::            http://msdn.microsoft.com/en-US/library/efy6s3e6(v=vs.80).aspx
:::
:::  Options:  Behavior may be altered by appending one or more options.
:::  The option names are case insensitive, and may appear in any order
:::  after the Replace argument. Options may be prefaced with / or -
:::
:::      /D  - Rename Directories instead of files.
:::
:::      /I  - Ignore case when matching.
:::
:::      /FM FileOrFolderMask
:::
:::            Only rename files or folders that match any of the pattern(s)
:::            using standard wildcards. Multiple patterns are delimited by a
:::            pipe (|). Only complete name matches count.
:::
:::              * matches any 0 or more characters
:::              ? matches any 0 or 1 character except .
:::
:::      /FX FileOrFolderExclusion
:::
:::            Exclude files or folders that match any of the pattern(s)
:::            using standard wildcards. Multiple patterns are delimited by a
:::            pipe (|). Only complete name matches count.
:::
:::              * matches any 0 or more characters
:::              ? matches any 0 or 1 character except .
:::
:::      /J  - Treat Replace as a JScript expression.
:::            The following variables contain details about each match:
:::
:::              $0 = the substring that matched the Search
:::              $1 through $n = captured submatch strings
:::              $off = the offset where the match occurred
:::              $src = the original source string
:::
:::            The following are also available:
:::
:::              $n = An incrementing number for use in the name. The value
:::                   is reset to the /NBEG value for each directory.
:::                   It increases by the /NINC value for each renamed file.
:::                   The value may be zero padded to the width specified by
:::                   the /NPAD value.
:::
:::              lc(str)
:::
:::                 Convert str to lower case. Shorthand for str.toLowerCase().
:::
:::              uc(str)
:::
:::                 Convert str to upper case. Shorthand for str.toUpperCase().
:::
:::              lpad(string,pad)
:::
:::                 Used to left pad string str to a minimum length. If the
:::                 str already has length >= the pad string length, then no
:::                 change is made. Otherwise it left pads the value with the
:::                 characters of the pad string to the length of pad.
:::
:::                 Examples:
:::                    lpad(15,'0000')    returns "0015"
:::                    lpad(15,'    ')    returns "  15"
:::                    lpad(19011,'0000') returns "19011"
:::
:::              rpad(string,pad)
:::
:::                 Used to right pad the string to a minimum length. If the
:::                 str already has length >= the pad string length, then no
:::                 change is made. Otherwise it right pads the value with the
:::                 characters of the pad string to the length of pad.
:::
:::              ts( {option:value, option:value...} )
:::
:::                 Perform date/time computations and produce formatted
:::                 timestamps. This function can get the current date/and time,
:::                 or get the created/lastModified/lastAccessed timestamps for
:::                 the file being renamed, or parse a date/time from the name
:::                 of the file, or use a user specified value.
:::
:::                 Use JREN /?TS() to get help on the ts() function
:::
:::              attr( [offChar] )
:::
:::                 Lists the attributes of the file/folder. Set attributes are
:::                 listed in upper case and unset attributes are shown as the
:::                 offChar, or lower case. The listed attributes are:
:::                   R - Read Only
:::                   H - Hidden
:::                   S - System
:::                   A - Archive
:::                   L - Link or Shortcut
:::                   C - Compressed

:: =============== ts() documentation ===============
::+
::+ts( [ { [option:value [,option:value]...] } ] )
::+ 
::+  A JScript function that can performs date and time computations and return
::+  a formatted time string.
::+ 
::+  The option object argument within curly braces is optional - if no argument
::+  is given, then it returns the current timestamp using compressed ISO 8601
::+  format with milliseconds and local time zone - YYYYMMDDThhmmss.fff+zzzz
::+ 
::+    Examples:
::+      ts()  - Current date/time:  YYYYMMDDThhmmss.fff+zzzz
::+      ts({dt:'created',fmt:'{iso-dt}'})  - The file create date:  YYYY-MM-DD
::+      ts({od:-1,fmt:'{YYYY}_{MM}_{DD}'}) - Yesterday's date:  YYYY_MM_DD
::+ 
::+  Option names are case sensitive. There are 5 types of options:
::+    1) Specify the base date          - dt:
::+    2) Specify date/time offsets      - oy: om: od: oh: on: os: of:
::+    3) Specify the output time zone   - tz:
::+    4) Specify the output format      - fmt:
::+    5) Configure the day-of-week and  - wkd: weekday: mth: month:
::+       month names for non-English
::+       users
::+
::+  Specify the base date and time
::+
::+    dt:  Value specifies the base date and time. Many formats supported:
::+
::+      Current local date/time
::+        - do not specify a dt: value
::+        - undefined value
::+        - empty string ''
::+
::+        Examples:
::+          dt:''
::+          dt:undefined
::+
::+      Milliseconds since 1970-01-01 00:00:00 UTC
::+        - NumericExpression (math OK)
::+        - NumericString (no math)
::+
::+        Examples:
::+          dt: 1391230800000          = January 1, 19970 00:00:00 UTC
::+          dt: 1391230000000+800000   = January 1, 19970 00:00:00 UTC
::+          dt:'1391230800000'         = January 1, 19970 00:00:00 UTC
::+          dt:'1391230000000+800000'  = error
::+
::+      String timestamp representation
::+        - Any string accepted by the JScript Date.Parse() method.
::+            See http://msdn.microsoft.com/en-us/library/k4w173wk(v=vs.84).aspx
::+
::+        Examples: All of the following represent Midnight on January 4, 2013
::+                  assuming local time zone is U.S Eastern Standard Time (EST)
::+
::+          dt:'1-4-2013'                  Defaults to local time zone
::+          dt:'January 4, 2013 EST'       Explicit Eastern Std Time (US)
::+          dt:'2013/1/4 -05'              Explicit Eastern Std Time (US)
::+          dt:'Jan 3 2013 23: CST'        Central Standard Time (US)
::+          dt:'2013 3 Jan 9:00 pm -0800'  Pacific Standard Time (US)
::+          dt:'01/04/2013 05:00:00 UTC'   Universal Coordinated Time
::+          dt:'1/4/2013 05:30 +0530'      India Standard Time
::+
::+      File timestamps to millisecond accuracy using WMI. Very slow, but
::+      locale agnostic. WMI call may not work on some older machines.
::+        - 'created'   = Creation date/time of the file
::+        - 'modified'  = Last Modified date/time of the file
::+        - 'accessed'  = Last Accessed date/time of the file
::+
::+        Example:
::+          dt:'created'  = creation date/time of the file to be renamed
::+
::+      File timestamps to second accuracy using FileSystemObject. Very fast,
::+      but locale dependent. May not parse properly for some countries.
::+        - 'fsoCreated'  = Creation date/time of the file
::+        - 'fsoModified' = Last Modified date/time of the file
::+        - 'fsoAccessed' = Last Accessed date/time of the file
::+
::+      Array with 2 to 7 numeric expressions (local time only)
::+        - [year,months,days,hours,minutes,seconds,milliseconds]
::+            year and months are required, the rest are optional
::+            Missing values are assumed to be 0
::+            Missing values are not allowed between specified values
::+            month 0 = January
::+            day 1 = First day of month, day 0 = Last day of prior month
::+
::+          Examples:
::+            dt:[2014,3,1,17,30,22,457]  = April 1, 2014, 17:30:22.457
::+            dt:[2014,0,1]               = January 1, 2014, 00:00:00
::+            dt:[2014,0]                 = December 31, 2013, 00:00:00
::+            dt:[2014,,10]               = error
::+
::+  Date/Time offsets and time zone options all use the same syntax.
::+  The value represents a numeric offset for the specified time unit.
::+  It may be expressed as a numeric expression (math allowed), or
::+  a numeric string (no math allowed). Both positive and negative
::+  values may be used.
::+
::+    oy:  Year offset
::+    om:  Months offset
::+    od:  Days offset
::+    oh:  Hours offset
::+    on:  Minutes offset
::+    os:  Seconds offset
::+    of:  Milliseconds (Fractional seconds) offset
::+
::+    tz:  Time zone used for output = minutes offset from UTC
::+
::+  The fmt: option is a string that specifies the format of the output.
::+  Strings within curly braces are replaced by dynamic components that are
::+  derived from the computed time stamp. Strings within braces that do not
::+  match a fmt: component are left as is. Strings not in braces are left
::+  as is. The format component names are not case senstive.
::+
::+  For example, a U.S. date would be represented as fmt:'{yyyy}/{mm}/{dd}'

Re: JREN.BAT - Rename files/folders using regular expression

#8 Post by dbenham » 09 Dec 2014 23:34

I got a private message from Brinda stating that the WMI calls to get the file timestamps was not working on Win 2000. There is also the issue that the WMI calls are quite slow.

So I added additional ts() dt: options to get FileSystemObject (FSO) timestamps instead of using WMI. This is much faster. There are two draw backs:

- FSO timestamps are only to second accracy - they do not have milliseconds.
- FSO timestamps are locale dependent - the timestamp will not parse properly in some countries.

The old WMI timestamps are accessed via dt:'created', dt:'modified', and dt:'accessed'.
The new FSO timestamps are accessed via dt:'fsoCreated', dt:'fsoModified', and dt:'fsoAccessed'.

I updated both the prior post as well as the current post at the top to version 2.1.

I updated version 2.1 to 2.2 to squash another bug.

At one point I had a /G option to make the Search global. I later opted to have all searches global, so I eliminated the /G option, but forgot to change my Search regex definition.

Version 2.2 fixes the bug by making all searches global.

Original line 684

Code: Select all

        search = BuildRegex( 'Search', args.Item(0), env('/G')?'g':'' + env('/I')?'i':'' ),

changed to

Code: Select all

        search = BuildRegex( 'Search', args.Item(0), env('/I')?'gi':'g' ),

dave,

sorry for late reply. thanks for helping on this

on win2000

previous code

Code: Select all

D:\test>jren ".*" "ts({dt:'modified',fmt:'{iso-dt} {iso-tm} {iso-tz}  '})+attr()+size('         ')+'  '+path()" /j /list /fm *.htm
Replace error: Invalid dt value


with the ammended code

Code: Select all

D:\test>jren ".*" "ts({dt:'fsomodified',fmt:'{iso-dt} {iso-tm} {iso-tz}  '})+attr()+size('         ')+'  '+path()" /j /list /fm *.htm

Re: JREN.BAT - Rename files/folders using regular expression

Thanks brinda.

My example was wrong. The ".*" search term matches both the entire line, plus the position at the end of the line, so it prints out the information twice.

The search term should be changed to "^.*", and then it works perfectly.

The old search term used to work until version 2.2 when I implicitly added the global attribute to the regex search. A Global search was my original intent all along.

I've updated the examples throughout the thread to compensate for the corrected behavior.

Ugh. Shouldn't have to support 6 MS operating systems.

Re: JREN.BAT - Rename files/folders using regular expression

Dave, have ya got a second to think about this one?

A task is to basically take 5 filenames at a time to echo into a file, and run a task - then repeat with the next five files.

I aimed to use a padded number - purely for cosmetic reasons in the output set of filenames -
and I was wondering if JREN has the ability to do both these things?

The task is listed here:
http://ss64.org/viewtopic.php?pid=8345#p8345

I'm trying to avoid using delayed expansion and stacks of calls and lots of manipulating,
and the jscript tools are so much more robust, and easier on the code.


I looked at Findrepl and thought of using the errorlevel to calculate where the next set of filenames was to start from but the /o:s:e doesn't seem to support a calculation - and as above I'm always trying to avoid delayed expansion.

If you're reading Antonio, did I miss a way to do it with Findrepl?

I don't see a simple solution using JREN, but it is fairly simple with JREPL. I've posted a solution at SS64.
