[TriLUG] awk question - or something better if you have it

[Kevin Otte via TriLUG]

Well, grep has Perl style regex:

kjotte at mystic:~$ nginx -V 2>&1 | grep -oP -- '--conf-path=\K([^\s]+)'
/etc/nginx/nginx.conf

I don't claim to fully understand what I just did as regex was never my
strong suit. I conglomerated from:
