Re^6: Data manipulation on a file

Have a look at the uniq and distinct functions from List::MoreUtils.

For example:

use Modern::Perl qw/2015/;
use List::MoreUtils qw/uniq/;
my @mountpoints = qw/one two three three two four one one five six/;

print join ' ', uniq sort @mountpoints;

Output: five four one six three two

No, you run it on the array. The argument to `uniq` is an array or list, not a string. In your script it will be `$outputstring .= "$filer:" . (join ' :', uniq sort @{$filer_hash{$filer}}) . ',';` (untested) CountZero A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout.
