I want to list all the jar files in subdirectories of a specified path, on a Windows computer, along with the file size & times.

dir /s gives me too much information. dir /s *.jar sort of does what I want, but gives me a bunch of information per-directory that I don't care about. dir /b/s *.jar is brief but doesn't give me the time or filesize.

Is there a command that will just list the jar files + filesize/time?

you could do this:

for /r %i in (*.jar) do echo  %~ti %~zi %i 

which will iterate over all dirs (including the current one) and echos out the *.jar names. It will also echo out the echo command, so you may want to pipe the output to a file:

for /r %i in (*.jar) do echo %~ti %~zi %i >> myJars.txt

or put it in a bat:

@echo off
for /r %%i in (*.jar) do echo %%~ti %%~zi %%i

note the double %'s in the .bat version.

  • To suppress the output of the 'echo' command, precede the command with '@'. for /r %i in (*.jar) do @echo %~ti %~zi %i

This command line works:

dir /s *.jar | find "jar"

It pipes the output of "dir" into the "find" command to filter it - filtering out lines not containing "jar" like the lines with "Directory".

However it is only 99.9% bullet proof. If a folder contains "jar" in its name AND this folder contains a jar file then you need to filter that out:

dir /s *.jar | find "jar" | find /V "Directory of"

"/V" means that all lines NOT containing "Directory of" will be printed on the screen.

The closest I was able to get to what you needed was

dir /p /s *.jar
This gives out the files' directory locations, their size, and their date/timestamp.

Excluding paths:

for /r c:\your\path %i in (*.jar) do @echo %~nxi %~zi %~ti

Including paths:

for /r c:\your\path %i in (*.jar) do @echo %~i %~zi %~ti

If there is no particular reason for using the command line (like a batch script need)
You could just use the Explorer, Search to list *.jar files from the base folder.
You will get the size and date information and the list can be sorted in a few ways.

This will be a GUI solution.
I always wondered why Windows does not allow me to export such a search result to CSV/XLS/TXT.
All that hard work of sifting through the folders goes waste; cannot post-process the output.
Anyone has ideas on such an export to file?
