chop $var
chop @list

Chops off the last character of a string contained in the variable $var (or strings in each element of a @list) and returns the character chopped. The chop operator is used primarily to remove the newline from the end of an input record, but is more efficient than s/\n$//. If no argument is given, the function chops the $_ variable.
