If you're a Python fan there is a nice tool to replace 'awk' and
similar tools:
svn checkout http://pyp.googlecode.com/svn/trunk/ pyp
I've patched this to include a 'balanced' (parenthesis, brackets,..)
With the original version I use
ifconfig wlan0 | /usr/local/bin/pyp
"pp.after('wlan0',2)|p[1]|p.re(r'(?<=inet )\d+\.\d+\.\d+\.\d+')"
If someone is interested in my patch I'm happy to share it,
Helmut.
