As you move into larger programs and scripts it
is a good idea to always use strict and warnings.
use strict;
use warnings;
After adding these to the top of your script
you'll need to use 'my' before using most variables
for the first time:
use strict;
use warnings;
for ( my $i; $i <= 5; $i++ ) {
sleep 1;
print "$i\n";
}
You can also use the range operator to save some
typing:
for my $i ( 1 .. 5 ) {
sleep 1;
print "$i\n";
}
