Get all IPs via ifconfig

Fetches the IPs and ONLY the IPs from ifconfig. Simplest, shortest, cleanest. Perl is too good to be true... (P.S.: credit should go to Peteris Krumins at catonmat.net) Show Sample Output

Get all IPs via ifconfig

and, a lot uglier, with sed: ifconfig | sed -n '/inet addr:/s/[^:]\+:$\S\+$.*/\1/p' Edit: Wanted to be shorter than the perl version. Still think that the perl version is the best..

What Others Think

Your command doesn't work in case of multiple IP. Actually all alternatives have this problemm, so don't be disappointed. Use 'ip' instead of ifconfig
