bug: quickget --list error fails due no non-portable use of tail

[blakemcbride]

Expected behavior

Get a list of available OSs.

Actual behavior

I get the list but I get the following two errors first:

tail: cannot open '+2' for reading: No such file or directory
tail: cannot open '+3' for reading: No such file or directory
tail: cannot open '+2' for reading: No such file or directory

Steps to reproduce the behavior

./quickget --list

Not seeing this on Ubuntu Mate with 4.9.5 (4547064) and I see the same errors are in the CURL section of quickreport ... Looks like we need to find the "feature" of Fedora 40 (Sway) that is not accounted for.

Ah : your tail is looking for +3 instead of supporting the +n syntax.

Can you please change tail + to tail -n + (in quickget or quickreport) and see if that fixes it for you.
