3.2.13 chomp

chomp LIST

This is a slightly safer version of chop (see below) in that it removes only any line ending corresponding to the current value of $/, and not just any last character. Unlike chop, chomp returns the number of characters deleted. If $/ is empty (in paragraph mode), chomp removes all trailing newlines from the selected string (or strings, if chomping a LIST).
