Nor "10-30-20".
What's the g-modifier for?
The structure is 'a;b;c;d', the smallest is 'a', so treat the ';' as the
start of a trailer.

Check out the module Set::IntSpan and see if it does what you want.

echo '1-10;25;33;100-250' | perl -nle '
/\A\d+(?:-\d+)?(?:;\d+(?:-\d+)?)*\z/ and print "$_ =OK"
'
But that also matches '12-3'.

Why not just use split()? Then you can do a simple regex on each
element:
###
use strict;
use warnings;
my $string = '1-10;25;33;1-00-250';
my @array = split(/;/,$string);
foreach my $element(@array){
if($element =~ /^\d+-?\d*?$/){
print "$element => valid\n";

You will need more than a r
