in reply to using basename on a list of filesnames
If you have a list of values and want to call a function on each of the values to make a new list, then you want to use map. I don't know where you're getting basename, so I just made a trivial example:
use strict; use warnings; sub rm_first_3_chars { my $name = shift; return substr($name, 3); } my @list_of_names = ("Fred", "Billiam", "Wozniapple"); @list_of_names = map { rm_first_3_chars($_) } @list_of_names; print join(", ", @list_of_names), "\n";
When run, it gives:
$ perl flp.pl d, liam, niapple
Essentially, you put the code you want to execute for each list item in the map block. In that block, $_ refers to each list item, and whatever the code returns is the new value that will be in the output list.
