Remove text between delimiters in linux

Question

Server got hacked and a fair amount of files were edited. We noticed that the code that was inserted were typically done between delimiters (e.g. /*e21234*/ blah blah /*/e21234*/). What is the most efficient way to remove this from a large number of files on a linux box? (I tried using sed but couldn't quite get it. I'm open to using perl or whatever would work)

Answer 1

Did you try this:

sed 's,/\*e21234\*/.*e21234\*/,,g'

But I agree that restoring a backup is probably best!
