#481 Command failed with exit status -1

[Syed Adeel Ahmed]

After upgrading usermin from 1.650 directly to 1.780, we are getting following message intermittently in output of our commands in 'Custom Commands' module

Command failed with exit status -1

We have verified that there is no error in the script running behind the scene in 'Custom Commands' and all exceptions are being captured and the script last line is 'exit 0'

It is even more confusing as the same command running as expected (without this message) while executed from Webmin > Others > 'Custom Commands' screen.

Is there a way we can suppress this message from usermin/webmin configuration? or is there a fix for this bug?

OS: Solaris 11.4
Browser: IE and Chrome (not tested on other browser)

Same here, still an issue in Webmin 1.955 on platform Solaris.

Does this still happen even for trivial commands, like "/bin/true" ?

[Joes Garage]

No, that's fine:

Output from /bin/true ..
No output generated

But f.e.:

Output from echo ""; echo ""; date; echo ""; /usr/lib/dns/rndc reload; sleep 2; tail -20 /var/adm/messages | grep named; echo ""; date ..

server reload successful

Command failed with exit status -1

This also happens if I put all into a new custom command.

[Jamie Cameron]

So does it fail for all scripts, and/or all lists of multiple commands?

[Joes Garage]

See some more test results (can you reproduce it on your solaris box, too?):
Output from /bin/true; /bin/true ..
No output generated

Output from /bin/true; /bin/false ..
No output generated
Command failed with exit status 65280

Output from /bin/true; date; /bin/false ..

Command failed with exit status -1

Also I would suggest to add three dots at the end of the Output line, as that is more common than only two.
