- chop
Chops off the last character of a string and returns the characterchopped. It is much more efficient than s/.$//s because it neitherscans nor copies the string. If VARIABLE is omitted, chops $_ .If VARIABLE is a hash, it chops the hash's values, but not its keys. You can actually chop anything that's an lvalue, including an assignment. If you chop a list, each element is chopped. Only the value of thelast chop is returned. Note that chop returns the last character. To return all but the lastcharacter, use substr($string, 0, -1) . See also chomp. |
