Perl has so many quick ways of doing things, I wonder if there is an
easy way to find out how many entries in an array match a string?
if I use the following to get a directory list of the sub directory
"things" into @gfnames, is there an easy way of find out how many of
the entries in @gfnames contain the string ".txt" without going
through and comparing each one?
(variant of Sinan's reply)
use strict;
use warnings;
opendir(BASE, "things");
opendir my $base_dir, 'things'
or die "Cannot open 'things' directory: $!";
@gfnames = readdir(BASE);
my @gfnames = readdir $base_dir;
my $txt_count = grep( /\.txt/, @gfnames );
closedir(BASE);
closedir $base_dir;
