Hello

ifconfig return :

eth0 Link encap:Ethernet HWaddr 11:24:1D:C1:99:BA
inet addr:192.168.0.1 Bcast:192.168.0.255 Mask:255.255.255.0

I would like somethings like

ADRESSE=$(ifconfig | sed -n '/addr:/,/Bcast:/p')
echo $ADRESSE
192.168.0.1

Help would be appreciated

$ /sbin/ifconfig lan | awk '/inet addr:/ { print substr($2, 6)}'
192.168.0.126

Great.

Thank you very much
