I would like to delete a php code on all my php files on my debian server. indeed I would like to get rid of a line: eval(base64_decode("DQplcnJvcl9yZXBvcnR")); It's present in many of my phpfiles. That's why I would like to find a script which is going to look it up in all my php files and replace itwith nothing? Do you have any idea how i could do that ? I know how to do it on windows with some software (notepad++ is very useful) but no idea how can I do that in a command line through ssh Thanks for your answer, Ans
