chomp

chomp $
var
 chomp @
list

Removes any line-ending characters of a string in $ var , or each string in @ list , that correspond to the current value of $/ (not just any last character, as chop does). chomp returns the number of characters deleted. If $/ is empty (in paragraph mode), chomp removes all newlines from the selected string (or strings, if chomp ing a list ). If no argument is given, the function chomp s the $_ variable.
