Hi I am trying to capture only the first occurence of a charcter

!this is a first level heading
!!this is a 2nd level heading

I only want to find the first item and not the second

current code

$line=~s/\!(^\![A-Z][a-z].+)/$1/gc;

This says to search for an exclamation mark, followed by the beginning
of the string (which makes no sense, of course), followed by another
exclamation mark, followed by a capital letter, a lowercase letter,
and then one or more of anything. And replace all of that with
everything except the first exclamation.

it either doesnt capture any ! or takes out the first ! when there is a double

No it doesn't. There is no way this pattern match ever succeeds.
It's not possible to find some character and *then* the beginning of
the string.

Provide sample input and output of what it is you're trying to do.
Your english description of the problem is confusing at best.
