Things are a little complicated. I've googled a sed script on: http://sed.sourceforge.net/grabbag/scripts/remccoms2.sh.txt But the script can't handle this testcase: printf("/* Haha \n"); /* Haha */ printf("// Haha \n"); // Haha I think a simple regular expression filter is not enough. A lexical parsing is required to ensure the results come out right in all cases. A prefessional utility is more suitable than a script written by me since I am not an expert in ANSI C standard. >AWK itself can do it, as can sed.
