I'd made a script for launching parallel rsync process:

#! /bin/bash
#echo "rsyncing From=$SRC_DIR To=$DEST_DIR RSYNC_OPTS=$RSYNC_OPTS"
echo $LIST|xargs -n1 -d, echo|xargs -n1 -P 0 -I% rsync --rsync-path='sudo rsync' ${RSYNC_OPTS} % ${DEST_DIR}

Then, I have problems to get the exit status of the rsync process. I know that is possible to get an array of pipestatus, but I need to catch the exit code to know if the rsync was made successfully or not.

This question came from our site for peer programmer code reviews.


Do you need to know the exact code or just whether it failed or not?

If you use GNU Parallel instead of xargs you can do:

echo $LIST | parallel -d, -P 0 rsync --rsync-path='sudo rsync' ${RSYNC_OPTS} {} ${DEST_DIR}

When it completes $? will contain how many jobs failed. To get the exact exit code use '--joblog file' to generate a tab separated file including exit code, or use '--halt 1' to get the exit code of the failing rsync in $?.
