:::
:::JSORT [File] [/Option [Value]]...
:::
:::  Sort lines of text from stdin and write the result to stdout.
:::  JSORT uses an ascending, case sensitive text sort by default.
:::
:::    File - If the optional File argument is specified, then JSORT reads lines
:::           from the file instead of from stdin. If specified, the File must
:::           be the very first argument.
:::
:::  Options:
:::
:::    /C n - Number of sorted lines to print. Skipped lines are always printed
:::           and do not contribute to the count. Default is -1 (all lines).
:::
:::    /D String - Specifies the string used to delimit tokens. The delimiter
:::           string is always case sensitive. A quote literal " must be escaped
:::           as \q, and a backslash literal \ must be escaped as \\.
:::           The default value is an empty string, meaning treat the entire
:::           line as a single token.
:::
:::    /I   - Ignore case when sorting (or when checking for uniqueness)
:::
:::    /N   - Sort consecutive digits as numbers instead of text. The numbers
:::           may be embedded within alpha text. JSort supports numbers up to
:::           20 digits long.
:::
:::    /O File - Writes the output to File instead of stdout.
:::
:::    /P n - Begin sorting at character position n relative to the beginning
:::           of the selected token. Lines that do not extend that far are
:::           treated as equivalent values, and collate before all other lines.
:::           The default value is 1 (first character).
:::
:::    /R   - Sort the lines in Reverse (descending) order.
:::
:::    /S n - Number of lines to skip - default is 0.
:::           Skipped lines are not sorted (remain in place)
:::
:::    /T n - Specify the token at which to begin sorting. The sort is not
:::           restricted to the selected token, it just helps to identify where
:::           to begin sorting. The default value is 1 (first token). A value of
:::           -1 represents the last token, -2 the penultimate token, etc.
:::           A value of 0 is invalid. Note that negative values only recognize
:::           tokens that occur after a delimiter. If the requested token cannot
:::           be found, then the line will collate before all other lines.
:::
:::    /U   - Only write unique lines (discard duplicates)

Original post:

I've often been disappointed that SORT did not have a case sensitive option, but never thought much about doing anything about it.

It's also not uncommon to want to sort strings with embedded numbers, and I've always parsed and reformatted the strings with 0 padded numbers so that I could use SORT. It works, but it's a pain.

But then at How can i order the results consecutively in a batch? rootx asked how to sort numeric strings. Squashman linked to the DosTips SortN.bat solution, which I had never noticed before. It works well, but it can be slow with moderate sized input.

Then I thought, why not write a hybrid JScript/batch SORT utility that can solve both problems efficiently and conveniently :?: :idea: - so I did :) I'm no JScript expert, and I did not spend much time optimizing the code. But it seems to work well in my limited testing. But be aware that the utility will load the entire input data set into memory, using more than twice the original space.

Full documentation is embedded within the script. Use JSORT /? to display the help.

Re: JSORT.BAT - Case sensitive sort with option for numeric

#2 Post by dbenham » 21 Oct 2014 13:50

There was an interesting StackOverflow question at Find top 10 processes with wmic command. JSORT.BAT could already sort numercally at a given line position, but it couldn't preserve the header, and it couldn't list just the top 10.

So I modified JSORT.BAT to include the /S n (skip n lines), and /C n (print top n sorted lines) options.

The solution becomes quite simple, and efficient. The only tricky bit is the position of the WorkingSetSize column varies depending on the longest listed file name. So extra code had to be included to compute the line position at which to start sorting.

Code: Select all

@echo off
setlocal

:: Get full proc list in unicode
wmic process list brief >procList.tmp

:: Convert unicode to ANSII
type procList.tmp >procList.tmp2

:: Read the header line
<procList.tmp2 set /p "header="

:: Identify position of WorkingSetSize column
for /f "delims=W" %%A in ("%header%") do echo %%A>skipSize.tmp
for %%A in (skipSize.tmp) do set /a pos=%%~zA-1

:: Print the header, followed by the top 10 sorted by WorkingSetSize
type procList.tmp2 | jsort2 /n /r /p %pos% /s 1 /c 10

:: Delete the temp files
del procList.tmp procList.tmp2 skipSize.tmp

Thank Dave, as always for your useful tools.

Just thinking that you might like to change the batch to provide help when no options are given.

No, JSORT is much like MORE or SORT - it is perfectly reasonable to run the command without any arguments or options, and it will wait silently for input, gathering everything that is entered, and then print out the sorted lines after <Ctrl-Z> is pressed.

Running it without any options performs a case sensitive sort.

Re: JSORT.BAT - Case sensitive sort with option for numeric

#7 Post by dbenham » 05 Nov 2014 17:02

I saw another StackOverflow question that led me to add yet another feature to JSort.

JSort now allows you to sort beginning at a given token position, rather than an absolute character position. The /T option specifies the token, and the /D option specifies the delimiter string (note - the delimiter can have length > 1). The /P option now specifies the position relative to the start of the selected token, rather than from the beginning of the string. The default token is 1, so it does not change the behavior when /T is not specified.

I also provide the option to specify the file to sort as the first argument, so you are no longer forced to use redirection or a pipe.

So, if given file test.txt:

Code: Select all

goodbye,Z570
Hello world,A100
Ivanhoe,Z36
tiddleywinks,B36
Variable length text,A9

Then the following command:

Code: Select all

jsort test.txt /t 2 /d "," /n

produces this output:

Code: Select all

Variable length text,A9
Hello world,A100
tiddleywinks,B36
Ivanhoe,Z36
goodbye,Z570

Re: JSORT.BAT - Case sensitive sort with option for numeric

Sweet! I am definitely going to use that option.
Just wondering if jsort would run faster if you could specify the output filename instead of redirecting stdout? Similar to the built in sort utility.

Re: JSORT.BAT - Case sensitive sort with option for numeric

Perhaps there is a small performance gain to be had, but I'm lazy :mrgreen:

As I said earlier, I've done very little to optimize the JScript code. It works fine for the small tasks that I've used it for, but it may not perform well with very large files. Given that the JScript loads the entire file in memory (twice over!), I suspect that the utility will completely fail at some size threshold.

I've implemented an /O option to specify the output file in lieu of using redirection. However, I took the easy way out and perform redirection within the batch code, so there is no performance benefit to using /O.

Version 3.2 also fixes a bug with the File argument implementation. Version 3.0 failed if the file path included an exclamation point (!). (Version 3.1 had major argument parsing bugs)

Version 3.2

Code: Select all

@if (@X)==(@Y) @end /* Harmless hybrid line that begins a JScript comment

::************ Documentation ***********
::JSORT.BAT version 3.2
:::
:::JSORT [File] [/Option [Value]]...
:::
:::  Sort lines of text from stdin and write the result to stdout.
:::  JSORT uses an ascending, case sensitive text sort by default.
:::
:::    File - If the optional File argument is specified, then JSORT reads lines
:::           from the file instead of from stdin. If specified, the File must
:::           be the very first argument.
:::
:::  Options:
:::
:::    /C n - Number of sorted lines to print. Skipped lines are always printed
:::           and do not contribute to the count. Default is -1 (all lines).
:::
:::    /D String - Specifies the string used to delimit tokens. The delimiter
:::           string is always case sensitive. A quote literal " must be escaped
:::           as \q, and a backslash literal \ must be escaped as \\.
:::           The default value is an empty string, meaning treat the entire
:::           line as a single token.
:::
:::    /I   - Ignore case when sorting
:::
:::    /N   - Sort consecutive digits as numbers instead of text. The numbers
:::           may be embedded within alpha text. JSort supports numbers up to
:::           20 digits long.
:::
:::    /O File - Writes the output to File instead of stdout.
:::
:::    /P n - Begin sorting at character position n relative to the beginning
:::           of the selected token. Lines that do not extend that far are
:::           treated as equivalent values, and collate before all other lines.
:::           The default value is 1 (first character).

Well then maybe that won't work for me then. I mostly work with very large files. Hundreds of megabytes and sometimes a gigabyte or two.

Can you give a large file a try and report back :?: I'm curious.

I successfully sorted a ~15 mb file in 64 seconds.

I attempted to sort a ~30 mb file and it failed with an "Out of memory" error. :evil:

So it looks like this utility is no good for large files - Sorry Squashman :(

How much ram do you have?

I know when I only had 1GB of ram on my computer I had issues reading large files with FOR /F because it also loads the whole file into memory first. I could usually process about a 600 MB file. Now I have a 4GB and can run larger files but is still pretty slow.
