- chop VARIABLE

- chop( LIST )
- chop

  Chops off the last character of a string and returns the character chopped. It is much more efficient than `s/.$//s` because it neither scans nor copies the string. If VARIABLE is omitted, chops `$_` . If VARIABLE is a hash, it chops the hash's values, but not its keys.

  You can actually chop anything that's an lvalue, including an assignment.

  If you chop a list, each element is chopped. Only the value of the last `chop` is returned.

  Note that `chop` returns the last character. To return all but the last character, use `substr($string, 0, -1)` .

  See also chomp.
