Re: SVN scripting

Hmmm DOS...

Okay. Instead of using /bin/false as the parameter for the --diff-cmd,
create a one-line batch script with "exit /b 2" as the sole command.
Then pass this batch script as the parameter to your --diff-cmd. That
will prevent the file differences from being outputted in the "svn
diff" command.

Also, you can use the DOS "find" command that seems to work somewhat
like awk and grep:

$ svn diff --diff-cmd false.bat -r $start:$end $url | find "Index: "

Of course, the best thing to do is to download ActiveState Perl
(http://activestate.com/Products/ActivePerl/?psbx=1) or Cygwin
(http://cygwin.com/) and use a real scripting language. Perl is more
universal and more powerful scripting language, but you need
administrative rights to load it on your machine. Cygwin doesn't need
administrative priveledges, and you also get a lot of other very
powerful tools with it.

And for both Cygwin and Perl, like Subversion, the price is right.
