Thank you very much for your help, but i have one more question, is this the
way that regex works or is it something in my code, every time i try to run
the script to search for a comma and replace it with a new line character
(\n) it just removes the commas but doesn't replace it with a new line
character.
What is it replacing them with? n's?
I'm betting your shell is swallowing the \, turning \n into just n. If that's true, you have to get a \ past the shell first. On my Unix box, both \\n and '\n' work.
Unfortunately, that doesn't solve your problem. Because then you'll replace ,s with a \ followed by an n. You want \n translated into a newline character, as it is in Perl's double quoted strings.
We could search your string for a \ followed by an n and replace it with a newline character, but that opens a another can of worms: What if you really wanted to replace with a \ and an n?
Given that, we can eval() your string to get Perl's string behavior. That'll do what you want in this case, but may complicate some other cases for you, say if you're making a CSV file and want to replace with "".
It's all tradeoffs.
Here's a simple change to eval() your string:
s/$search/qq("$replace")/eeg; # update your search to thisHope that helps.
