Batch file - storing results of exe command

I want to execute a command in my batch file, and store those results for later use in the same batch file. Anyone know how to do this? Below is what I have so far.


@ECHO OFF
SET REPOS=%1
SET REV=%2
SET WORKSPACE=D:\apache\htdocs

REM I want to execute svnlook.exe and store its results (list of path values) in CHANGES
SET CHANGES="svnlook changed %REPOS% -r %REV%"

ECHO. %DATE% >> D:\svn_log.txt
ECHO. %TIME% >> D:\svn_log.txt
ECHO. %WORKSPACE% >> D:\svn_log.txt
ECHO. %REPOS% >> D:\svn_log.txt
ECHO. %REV% >> D:\svn_log.txt
ECHO. %CHANGES% >> D:\svn_log.txt

FOR /F %%a IN (`%CHANGES%`) DO (D:\Subversion\bin\svn.exe update %%a)

I think you can execute the svnlook and put the result in a temp file and then read the text from that file and append it to svn_log.txt.

I do not know what your command does but you can try something like that:
svnlook changed %REPOS% -r %REV% > D:\tmp_log.txt


The output of the execution will be put in a file.

snvlook cmd returns files that have been modified in the following format:
U dev\trunk\application\test.php

Using FOR /F "usebackq" %%a IN (`svnlook changed %REPOS% -r %REV%`) DO (svn update %%a & ECHO. %%a >> D:\svn_log.txt)

The svn_log.txt file shows only the "U" - I need the test.php filename instead. How can I get that?

simply write this:
svnlook changed %REPOS% -r %REV% >> D:\svn_log.txt


and this will append the output of the file svnlook to the svn_log.txt file.
