Duplicity

Get the exit status of duplicity

Asked by Henrik

I'm writing a shell script to handle the backup of one of our servers. I'm creating an error_handler that I want to call when a duplicity call fails or crashes, but I'm unable to find this out by checking the exit status of a duplicity run since it always seems to return 0. If it succeeds, if it fails because of incorrect params, if it crashes / throws an exception during execution, it always returns 0.

The way I'm currently trying to check this is by doing,

duplicity --force /root $REMOTE/$REMOTEBASEDIR/root
if [ $? != 0 ]; then
..

$? is always 0. How can I see if it has failed/crashed?

Thanks in advance!

what's your duplicity version?

can you give an example with console output where duplicity fails with a success exit code (0) ?

Hmm I realized I was checking it the wrong way.. it actually works. I guess I had to write you that question in order to think about the correct way :) Sorry for waisting your time.
