pop

See the current Perl documentation for pop.

Here is our local, out-dated (pre-5.6) version:


pop - remove the last element from an array and return it



pop ARRAY

pop



Pops and returns the last value of the array, shortening the array by 1. Has a similar effect to

    $tmp = $ARRAY[$#ARRAY--];

If there are no elements in the array, returns the undefined value. If ARRAY is omitted, pops the @ARGV array in the main program, and the @_ array in subroutines, just like shift().
