You might be better off asking questions like this on a dedicated Perl forum like Perl Monks (http://perlmonks.org/) or on a mailing list like the Perl beginners list (http://lists.perl.org/list/beginners.html). But I'd probably do something like this: #!/usr/bin/perl use strict; use warnings; foreach (<DATA>) { s/\.?0+$//; print; } __END__ 1.20 1.00 1.25 Cheers, Dave... -- users mailing list users@lists.fedoraproject.org To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
