Variables Basic List Functions

Another way to add or remove elements from a list is by using one of Perl's four built-in list manipulation functions

@foo = ( "a", "b", "c", "d" );

Add "e" to the END of @foo

push( @foo, "e" );

Remove "e" from the END of @foo

$e = pop( @foo );

Add "a" to the START of @foo

unshift( @foo, "a" );

Remove "a" from the START of @foo

$a = shift( @foo );
