Exit with ssh command's exit code

[solution-al]

We have multiple hosts with executing long running tasks having a lot of output. We would like to exit dssh with non-zero exit code if any of the commands failed with non-zero exit code.

For example:

dssh -l "server1 server2" "invalid-command"
echo $?

Output of $? should be non-zero as is with running regular ssh:

ssh server1 "invalid-command"
echo $?

This is needed so that we could check for it and exit out wrapper script with non-zero exit code to hint that we should check logs to understand what went wrong in which server. Since currently dssh exits with code 0 it's impossible to do that.

Hmm, that's a great point. It probably wouldn't be much of an issue to fix this, either. Let me take a look...

We ran into the issue described above where one of the commands failed on one of the servers and we didn't notice it since dssh exit code was 0. Did you have time to look into this issue yet so that this problem would be fixed?

I pushed a potential fix for this to the 'exit-status' branch... Haven't tested it much yet, but it should propagate the exit statuses and give you a non-zero result if any of the commands returned a non-zero exit code.
