chop

  • 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) .
