f.each_with_index { |line,lineno| ... } is a simple way to iterate over 
the lines and have the line number (starting at 0) too.

I should point out that Ruby does inherit this horrible Perlism:

$ ruby -ne 'print if /sshd/../ntp/' </etc/passwd
sshd:x:109:65534::/var/run/sshd:/usr/sbin/nologin
openwrt:x:1009:100::/home/openwrt:/bin/sh
ntp:x:115:115::/home/ntp:/bin/false
$

But for sanity reasons you should probably avoid it.
