pop
  • pop ARRAY
  • pop
  • Pops and returns the last value of the array, shortening the array by one element. Has an effect similar to

        $ARRAY[$#ARRAY--]

    If there are no elements in the array, returns the undefined value (although this may happen at other times as well). If ARRAY is omitted, pops the @ARGV array in the main program, and the @_ array in subroutines, just like shift.
