Supervisor: no such file or directory even though it is there

Question

I am trying to start supervisor service supervisor start, as root, but it gives me

env: /etc/init.d/supervisor: No such file or directory

Yet, I can clearly see that file exists:

[root@master vagrant]# ls -l /etc/init.d/ total 256

And it contains some script, as expected.

What am I doing wrong?

Solution

It's not complaining about the /etc/init.d/supervisor file itself, but most likely about the file it wants to execute as - usually the shell that appears on the shebang line in that file. It's a somewhat misleading error that I've seen many times before.

I disagree that this is a duplicate of the marked question. In the marked question, it was clear that something about the first line of the script was wrong, whereas here, it was not clear (at least to me) where the error even was. The benefit of the answer to this question is stating that the error is in the first line. Only with this knowledge given is the linked question helpful. However I agree it is closely related.

That was /bin/bash... but the file for some reason had windows newlines, and that's why /bin/bash^M wasn't found!? Thanks, that was it! :-) I think the problem is that I checked out a git repo on windows and used the files in a Linux VM, probably the line endings were changed at check-out. I need to check the rest now...

Yeah, ^M's are what usually pop that error message up for me, too. That's why I'm so appreciative to whomever wrote dos2unix.
