Re: parallel error while parsing options

[Gabriel Ganne]

Hi,

With Devel-Trace, I found the issue.

It seems the pidtable expects to match a line with two pids (numbers) folloed by a mandatory string, but for some reason I only have the pids.

So I made that last part optional, and it seems to do the trick.

Thank you for your help.

I've now set up a CentOS 7.2.x x86-64 VBox VM and built and installed GNU
parallel and it seems to run fine - tested the --help flag and a sample
invocation - see the screenshot at:

Some things you can try to diagnose the problem:

1. Devel-Trace - https://metacpan.org/search?q=devel%20trace&size=20 - you can
use perl -d:Trace `which parallel` and see what it gives you.

2. strace.
