First, see if you even get any output with the code you first listed:
Code:
#! /bin/bash

cat wtmp | strings | egrep "[0-9]+\.[0-9]+\.[0-9]+\.[0-9]" | sort -u

(note: i took the -o option out of egrep ... i don't have that option so it gives me an error)

If that works, try this and see if you get anything on screen:
Code:
#! /bin/bash

cat wtmp | strings | egrep "[0-9]+\.[0-9]+\.[0-9]+\.[0-9]" | sort -u | while read LINE; do echo $LINE; done

If that works, then I want you to actually list a few real lines from input.txt so I can see what that file looks like.
