I have a task defined in Supervisor that I would like to invoke hourly from /etc/cron.hourly. I can run it manually, but not from run-parts:

$ sudo supervisorctl start my-task -- works

# . /etc/cron.hourly/my-script -- works

$ sudo run-parts --report --test /etc/cron.hourly -- lists my-script as expected

$ sudo run-parts --report /etc/cron.hourly -- fails with:

run-parts: failed to exec /etc/cron.hourly/my-script: No such file or directory
run-parts: /etc/cron.hourly/my-script exited with return code 1

The contents of /etc/cron.hourly/my-script is:

/usr/bin/supervisorctl start my-task

I have confirmed that:

What am I missing?

  • Why the link to ubuntuforums? Are you saying that you solved the problem, and it was a non-unix style line ending? – Jos Jun 14 '16 at 10:22
  • @Jos updated question, it was a problem, but sadly not the fix – d3vid Jun 14 '16 at 10:30
  • Despite the wording failed to exec /etc/cron.hourly/my-script: No such file or directory I think your script does get executed. Is there anything useful in the Supervisor log? Can you add some more debugging to your script, like echo $(date) >> /tmp/debugfile or something? – Jos Jun 14 '16 at 10:50
  • @Jos in fact, my first fix fixed it, but I forgot to chmod; I've reverted the question for clarity -- but thanks for the comment, it got me thinking! – d3vid Jun 14 '16 at 11:37

I created my-script on Windows, so the shebang was correct, but had a Windows line ending. This will cause a cron script to fail. Recreating the script on Ubuntu (and chmodding it etc) fixed the problem.
