Two simple ways to do this, depending if you have sed or not.
ifconfig eth0 | grep "inet addr:" | cut -f 2 -d : | cut -f 1 -d " "
ifconfig eth0 | grep "inet addr" | cut -c 21-35 | sed "/ /s///g"
or even in perl
#!/usr/bin/perl
$ip = `ifconfig eth0`;
$ip =~ m/inet addr:(\d+\.\d+\.\d+\.\d+)/;
$ip = $1;
Of course these depend on your ifconfig spitting out the same output as
mine did. netstat -rn or something could have been used too actually,
probably easier too.
netstat -rn | grep eth0 | cut -f 1 -d " "
shoud work.
