Question Delete same lines out of file.
hello... I have a file with a list of filepaths in it, like so:

delMe.txt (files to be deleted)
Code:
./root/index.php
./root/language/se/home.inc.php
./root/language/pl/home.inc.php

Now here's what I'm trying to do. I want any lines in the above file (delMe.txt) to be deleted out of the original file they came from (below, orig.txt):

orig.txt
Code:
./root/includes/goobermods/Must_Login/index_inc.php
./root/index.php
./root/language/se/home.inc.php
./root/language/nl/home.inc.php
./root/language/fi/home.inc.php
./root/language/en/home.inc.php
./root/language/fr/home.inc.php
./root/language/es/home.inc.php
./root/language/pl/home.inc.php
./root/language/dk/home.inc.php
./root/language/cn/home.inc.php
./root/language/sk/home.inc.php
./root/language/pt/home.inc.php
./root/language/no/home.inc.php
./root/modules/gateway/index.php
./root/test/index.php

I started to do something like this (but think i'm making it complicated)
Code:
#!/bin/bash

lines=`cat delMe.txt | wc -l`

for i in `seq 1 $lines`
do
    sed -n $ip delMe.txt | xargs grep orig.txt...??
    #I HAVE NO IDEA AT THIS POINT ^^
done

thanks a bajillion in advance!!
