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, resetting the each iterator in the process.

  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) .
