So, the warning is about the use of double-quotes when single-quotes will work just fine. I wrote a new script and changed it to single quotes, so for consistency, I looked at other Perl scripts that might have the issue. The message I got was: /root/add_commit_links.pl: Useless interpolation of literal string at line 51 near 'my $tmpfile = $file . ".tmp";'. (Severity: 1) My $HOME/.perlcritic has: severity = 1 and that is why I saw it.
