Write to existing file with character insertby Mark.Allan (Sexton)

Mark.Allan has asked for the wisdom of the Perl Monks concerning the following question:
Not sure how this can be so hard but here goes, im trying to search for files in a directory which match a certain pattern, this is easy, when I find these files I want to read through them, search for a string which matches a specific pattern then edit these files by adding an # at the start of the matched line.
Can I do this with one search and replace by appending the current file and editing. I thought this would be simple, it probably is for you gurus but I'm only an "occasional" scripter
Here is what I got so far. I could have multiple files called rc.itm1 or rc.itm2 etc in the /etc dir. So I need to find these files, edit a line which matches "start ux" by inserting an # at the beginning of line
Current code finds the files, finds the string, and prints the string with an # in front but I'm struggling to work out how to successfully search and replace this string in the same file and save it off.
Can anyone help me out please?
