in reply to Check if at least one element of array is bigger than X

but not print it 4 times

The other solutions are better, but you could just print the message the first time only (untested): 
my $mess = 1;

foreach $i(@array) {
  if($i > 10) {
    print "Bigger than 10" if $mess;
    $mess = 0;
  }
}

$mess = 1; # In case we want to use it again.

This would allow you to (if needed) iterate through the whole loop, but display the message only once.

Cheers,
Rob

    More than one way to skin a cat:

    #!/usr/bin/perl
use strict;
use warnings;

my @array = (1..10);
my $found = 0;
for (@array) {
    $found ++ if $_ > 10;
}

print "Bigger than 10" if $found;
