Re: Backup and Incremental Backup Perl Scripts

Hi Trystan

shift takes the first item of an Array (a List) and returns it.
Its like push and pop on registers but on the begin of the list.

If you don't give any argument to shift it will use @ARGV (or @_ in a
subroutine).
So you _can_ omit the @ARGV if you want to:

my $var1 = shift;
my $var2 = shift;
or
my ($var1, $var2) = @ARGV;

Also take a look at:
$ perldoc -f shift
