Common List Functions in Perl

Part of the Perl For Dummies Cheat Sheet

Perl was originally designed to help process reports more easily. Reports often contain lists, and you may want to use Perl to perform certain functions within a list. The following table shows you common list functions, their splice equivalents, and explains what the function does:

Function splice Equivalent What It Does
push (@r, @s) splice(@r, $#r+1,0, @s) Adds to the right of the list
pop (@r) splice(@r, $#r, 1) Removes from the right of the list
shift (@r) splice(@r, 0, 1) Removes from the left of the list
unshift (@r, @s) splice(@r, 0, 0,@s) Adds to the left of the list
