detect svn changes in a .bat

Question

I have a .bat and inside the .bat i would like to execute a special code if there's some modification inside the svn repository (for example, compile).

Answer 1

For Win 2000 and later, this would assign the last output row from the svn status commmand to the svnOut variable and then test if the variable contains anything:

@echo off
set svnOut=
set svnDir=C:Your\path\to\svn\dir\to\check
for /F "tokens=*" %%I in ('svn status %svnDir%') do set svnOut=%%I

if "%svnOut%"==""  (
    echo No changes
) else (
    echo Changed files!
)

Why there is a line like this

set svnOut=

you have to figure out yourself. ;-)
