This question already has an answer here:

I have malicious code in every php file. This malicius code is auto paste at the beginning of file. I want to remove this with UNIX command from console.

This is malicious code:

<?php $guobywgpku = '..... u=$bhpegpvvmc-1; ?>

I write this RegExp,

"/<\?php \$guobywgpku.*\?>/m" 

and this RegExp work. I tested it here.

The problem is, write command which remove this malicious code from every php file on the sever. Please Help me.

Now i have something like this.

sed "/<\?php \$guobywgpku.*\?>/m" index.php
