chopSee the current Perl documentation for chop. Here is our local, out-dated (pre-5.6) version: chop - remove the last character from a string
chop VARIABLE chop LIST chop
Chops off the last character of a string and returns the character chopped.
It's used primarily to remove the newline from the end of an input record,
but is much more efficient than
while (<>) { chop; # avoid \n on last field @array = split(/:/); #... } You can actually chop anything that's an lvalue, including an assignment:
chop($cwd = `pwd`); chop($answer = <STDIN>); 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). |
