I'm trying to back up our svn repositories, and I found a nice
little backup command line bzip's the backup and creates the md5

svnadmin dump --deltas /repo |bzip2 |tee dump.bz2 | md5sum >dump.md5
The problem is I need to split the backups, so this doesn't really
work. Is there perhaps another way of piping things to allow for
splitting of the backups? Currently I'm doing something like this
svnadmin dump --deltas /repo |bzip2 |split - -b 64m
cat *.bz2* | md5sum >dump.md5
Is there a way to do this all in one step?
What about:
svnadmin dump --deltas /repo | bzip2 | tee >(split -b 64m -
dump.bz2.) | md5sum > dump.md5

Sorry to resurrect an old thread, but even though this works fine from
the command line, it doesn't seem to work from my perl script. I get
sh: -c: line 1: syntax error near unexpected token `('
sh: -c: line 1: `svnadmin dump --deltas /svn/russ

/backup/russ/2007/12/full.4.md5'
Looks like it's running sh instead of bash? Is there a way to change
the shell that executes the command? I'm using backticks to execute the
command in perl.
