Leonid, the problem was to process many files at the same time. One of the hosting accounts was compromised by a virus on one (or more?) of the client’s computers that appended a malicious JavaScript to all PHP/HTML files

Thanks for the tip though!

If you are using a real text editor, you can do it with one command without leaving to shell.

That seems like an awful lot of code for what sed does out-of-the-box.

#!/bin/sh

sed /$2/d $1 > $1.xx && mv $1.xx $1

./rdel.sh file_to_process needle
