NAME

chop - remove the last character from a string

SYNOPSIS

chop VARIABLE

chop LIST

chop

DESCRIPTION

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).
