Or another variation on the same theme without the overhead of perl:
ifconfig eth0 | grep inet | awk -F: '{print $2}' | cut -f1 -d' '
Though I think Ben's idea is actually faster:
$ time ifconfig eth0 | grep inet | awk -F: '{print $2}' | cut -f1 -d' '
10.1.8.94
real 0m0.021s
user 0m0.000s
sys 0m0.010s
$ time ifconfig eth0 | perl -ne 'print "$1\n" if m/inet addr:([0-9.]*)/;'
10.1.8.94
real 0m0.015s
user 0m0.000s
sys 0m0.010s
You can tighten this up a little too:
ifconfig eth0 | perl -ne 'print "$1\n" if /addr:([0-9.]*)/;'
but all it saves are a couple keystrokes :)
