youngest trunk revision?

Hello,

   I would like to know the youngest revision of only the trunk of my
repository. I know "svnlook youngest RPATH" will tell me the latest revision
number, but it tells the latest for the entire repository - not just the trunk.

  The reason I would like this number is because I would like a cron job that
monitors the respository and automatically creates a snapshot tarball, but
only when the repository has changed since the last tarball. I suppose I could
throw perl at it and extract the information from some other commands, but is
there a better way?

Thanks,
Alex

P.S.- post hooks are not a good solution since the commits may be too frequent
for the tarball to be made before the next commit.

svn log $URL_OF_TRUNK --limit 1 -q | awk '/^r/ { print $1 }

You could, however, use a very short hook script to see if the commit  
is happening on trunk, and if so, record the revision number in a  
file. Then the cronjob could read that file to determine the youngest  
revision of trunk.
