Open the directory with opendir, then call sort on your readdir. You might want to use file tests -X to see if you have only files. Something like the following may work: `opendir DIR, $dir or die "Can't open $dir: $!"; my @files = sort grep { -f "$dir/$_" } readdir DIR; # work with @files` [download]	[reply] [d/l]

If you want the files in the current directory, you could do something like this: `my $somedir = '.'; opendir DH, $somedir or die "Cannot open $somedir: $!"; my @files = grep { ! -d } readdir DH; closedir DH;` [download]	[reply] [d/l]

File::Slurp offers a shortcut for the opendir/readdir/closedir idiom: `use File::Slurp; my $dir = '.'; # or whatever my @files = sort grep { -f "$dir/$_" } read_dir($dir);` [download] Note that `File::Slurp::read_dir` automatically skips '.' and '..'.	[reply] [d/l] [select]

Or how about using this? Seems a bit easier and shorter `my @files = <>;` [download] or you can do this if you want a list of files only (not directories) `my @files=(); while (<>) { push (@files,$_) if (-f "$_"); }` [download]	[reply] [d/l] [select]
