I spend a lot of time updating a variety of different repositories of different varieties and denominations, and I hate having to do that all by hand – I’d rather just go up into a top-level directory and say update-all and let a script work out what to do, no matter what different repos are there. I do it with a function defined within my bash profile/rc scripts, and it covers git, bzr, svn, bk, and cvs. The trick is to identify what type of directory we are updating. I do this, lazily, for each type individually, rather than for each directory, but I’ve found this method to be more reliable.

update-all () { for file in `ls -d */.svn 2>/dev/null`; do realdir=`echo $file|cut -d/ -f1`; echo Updating in $realdir; ( cd $realdir; svn update ); done; for file in `ls -d */.bzr 2>/dev/null`; do realdir=`echo $file|cut -d/ -f1`; echo Updating in $realdir; ( cd $realdir; bzr pull ); done; for file in `ls -d */.git 2>/dev/null`; do realdir=`echo $file|cut -d/ -f1`; echo Updating in $realdir; ( cd $realdir; git pull ); done; for file in `ls -d */CVS 2>/dev/null`; do realdir=`echo $file|cut -d/ -f1`; echo Updating in $realdir; ( cd $realdir; cvs up ); done; for file in `ls -d */BitKeeper 2>/dev/null`; do realdir=`echo $file|cut -d/ -f1`; echo Updating in $realdir; ( cd $realdir; bk pull ); done; unset realdir}

That’s it – a quick way to update any directory of repos.
