DIR output including path on the same line as file name?

I want a compact DIR output that has path, name, size and date on the same line, like "Details" view of F3 search results in Windows.
DIR /S FOO.TXT | FINDSTR /C:":" achieves the compact wish, one line per filename, but of course size and path are missing because they're not on the same line in standard DIR output.
/B seems to be the only choice that shows the path and file on the same line, but it really is bare and doesn't have size and date.

The FOR command is your friend.
Code: Select all
In addition, substitution of FOR variable references has been enhanced.
You can now use the following optional syntax:
%~I - expands %I removing any surrounding quotes (")
%~fI - expands %I to a fully qualified path name
%~dI - expands %I to a drive letter only
%~pI - expands %I to a path only
%~nI - expands %I to a file name only
%~xI - expands %I to a file extension only
%~sI - expanded path contains short names only
%~aI - expands %I to file attributes of file
%~tI - expands %I to date/time of file
%~zI - expands %I to size of file
%~$PATH:I - searches the directories listed in the PATH
environment variable and expands %I to the
fully qualified name of the first one found.
If the environment variable name is not
defined or the file is not found by the
search, then this modifier expands to the
empty string

Thank you. I would have never thunkit.

test.bat
for /R c:\ %%I in ("ipconfig.txt*") do @echo %%~tI ... %%~zI ... %%~fI
Note the asterisk.
This gives (run from c:\, but I assume the /R parm makes that a moot point) the correct 2 files
01/20/2018 09:59 PM ... 8424 ... c:\ipconfig.txt
01/20/2018 09:59 PM ... 8424 ... c:\foo\ipconfig.txt
That's fine (although I fought and fought and failed trying to get anything to work with single ' instead of ").
Yet if I run it with the filespec asterisk removed
for /R c:\ %%I in ("ipconfig.txt") do @echo %%~tI ... %%~zI ... %%~fI
it seems to match everything in the world
... ... c:\"ipconfig.txt"
... ... c:\$Recycle.Bin\"ipconfig.txt"
... ... c:\$Recycle.Bin\S-1-5-18\"ipconfig.txt"
... ... c:\$Recycle.Bin\S-1-5-20\"ipconfig.txt"
... ... c:\foo\"ipconfig.txt"
... ... c:\foo\bar!_files\"ipconfig.txt"
etc. etc. etc. for hundreds of files before I Control-C
Now if I say to start in c:\batch,
for /R c:\batch\ %%I in ("ipconfig.txt") do @echo %%~tI ... %%~zI ... %%~fI
it doesn't return a line for every file in the dir; it returns just one line
... ... c:\BATCH\"ipconfig.txt"
but there is no ipconfig.txt in c:\batch. I assume that the one line returned "represents" the directory entry in the root ... that is, c:\batch\..
At any rate I'm deeply confused.

Also, per FOR /?, wasn't I supposed to go
setlocal enableextensions
first, in order to use /R ? (It seems to make no difference if I include it)
FWIW I'm running on Win 7. VER is
Microsoft Windows [Version 6.1.7601]
Is enableextensions automatic for some DOS versions?

The FOR loop only checks for the existence of a file if globbing is applied (that is, if you use a pattern that contains wildcard characters).
DOS does not even support something like command extensions. Assuming you are talking about Windows the answer is yes. Extensions are enabled by default at least since XP (maybe earlier). But it's a registry setting which means that you could change this default.

In response to the last post,
---------------------------------------------------------------------------------------------------------------------------------------------
The basis of my question about command extensions, which I thought was based on enableextensions:
{FOR /?}
...
If Command Extensions are enabled, the following additional
forms of the FOR command are supported:
...
FOR /R
---------------------------------------------------------------------------------------------------------------------------------------------
and "globbing" (or even wildcards) is not explained below for FOR /R, so I suppose you have moved me closer to some understanding.
{FOR /?}
FOR /D %variable IN (set) DO command [command-parameters]
If set contains wildcards, then specifies to match against directory
names instead of file names.
FOR /R [[drive:]path] %variable IN (set) DO command [command-parameters]
Walks the directory tree rooted at [drive:]path, executing the FOR
statement in each directory of the tree. If no directory
specification is specified after /R then the current directory is
assumed. If set is just a single period (.) character then it
will just enumerate the directory tree.
-------------------------------------------------------------------------------------------------------------------------------------------
Looks like I need to put in a few more hours of trial and error on this.

ss64 clarified the asterisk when using /R
"Unlike some other variants of the FOR command you must include a wildcard (either * or ?) in the 'set' to get consistent results returned. In many cases you can work around this by adding a single character wildcard e.g. if you are looping through multiple folders to find the exact filename myfile.txt you could instead specify myfile.t?t"

This (namely the NOTES at the bottom of the .BAT below) shows the kind of information I was looking for, which I'll share in case it is helpful and useful to those less than superguru, some of whom don't have those details all committed to memory. There may be inaccuracies but it's what I deduced. The NOTES at the bottom include some important caveats - again, my own deductions, so take with a grain of salt.
Code: Select all
: alt_dir.bat
: This is an alternate homemade dir producing output like
: 01/20/2018 09:59 ... 8424 ... c:\ipconfig.txt
: 01/20/2018 09:59 ... 8424 ... c:\foo\ipconfig.txt
: This is handy for Win 7+ where productive 32 bit file management apps
: don't work, and you want a compact listing, but don't want to do an F3 search
: dir ipconfig.txt /a /s doesn't get path, size and dir on same line
: Directory of c:\ipconfig.txt
: 01/20/2018 09:59 PM 8,424 ipconfig.txt
: etc.
:
: Here's the way to got the output shown atop:
for /R c:\ %%I in (ipconfig.txt*) do @echo %%~tI ... %%~zI ... %%~fI
: A fine way to understand .BATs is ss64, and in this case,
: https://ss64.com/nt/for_r.html
: Note, /R is to include subdirs
: Note, double %% needed in a batch file
: Note, with /R, a wildcard symbol is needed, even nonsensical as above
: Note, (ipconfig.txt*) could be ("ipconfig.txt*") but ('ipconfig.txt*') pukes
: Note, variables %I (and %%{TILDE}tI, etc.) are Case Sensitive.
: Note, {TILDE} is used above, not ~ because even in rem or : it expands!
: (though proper delimiting could have managed that)
: Note, omitting c:\ would start in the current dir
By the way, that irritating wildcard requirement actually bit me, producing ipconfig.txt.lnk - grrrr.

Code: Select all
for /f "delims=" %%i in ('2^>nul dir /a-d /b /s "C:\ipconfig.txt"') do ...
Nobody did ever say that you can't apply modifiers ~t and ~z if you process the output of the DIR command
