in thread Stat and file size

I would write this a little differently to guard against a directory that has lots of files. The below example iterates over the directory handle instead of adding the directory filenames to an array. I also added more error checking to give a tighter example.

use strict; use warnings; my $testfolder = './test'; my @newfiles; if ( opendir(my $dir, $testfolder) ) { while ( my $file = readdir($dir) ) { # skip parent and current directories next if ($file eq '.' || $file eq '..'); # skip directories next if (-d $file); # create the fullpath my $full_pathname = $testfolder . "/" . $file; next unless (-e $full_pathname); # get the filesize my $filesize = -s $full_pathname; # push the non-zero sized file to the new file array if ($filesize) { push(@newfiles,$file); } } closedir($dir); } else { die "[Error] UNABLE TO OPEN DIRECTORY: [$!]"; } foreach my $file (@newfiles) { print "$file\n"; }
