Description frater 2009-07-28 08:29:03 UTC 
I like to use "egrep -o" in scripts where I want to parse a certain expression...

I have a DD-WRT router and also have optware installed so I can do a direct comparison.

root@WAN:~# nvram get wl0_maclist 2>/dev/null | egrep -o '([[:xdigit:]]{2}[:-]){5}[[:xdigit:]]{2}'

root@WAN:~# nvram get wl0_maclist 2>/dev/null | /opt/bin/egrep -o '([[:xdigit:]]{2}[:-]){5}[[:xdigit:]]{2}'
