i wanted list the names of all the files in a directory, except for "." and ".."
but i think it doesnt work properly
#!/usr/bin/perl
use strict;
use warnings;
my $dir = $ARGV[0] || $ENV{HOME};
my @files;
if (-d $dir){
opendir (my $DIR, $dir);
@files = grep {/^(?!\.{1,2}\z)/} readdir($DIR);
closedir($DIR);
} else {
die("can't open the dir, $dir\n");
}
foreach my $file (@files) {
print "$file\n";
}
