readdir

See the current Perl documentation for readdir.

Here is our local, out-dated (pre-5.6) version:


readdir - get a directory from a directory handle



readdir DIRHANDLE



Returns the next directory entry for a directory opened by opendir(). If used in list context, returns all the rest of the entries in the directory. If there are no more entries, returns an undefined value in scalar context or a null list in list context.

If you're planning to filetest the return values out of a readdir(), you'd better prepend the directory in question. Otherwise, because we didn't chdir() there, it would have been testing the wrong file.

    opendir(DIR, $some_dir) || die "can't opendir $some_dir: $!";
    @dots = grep { /^\./ && -f "$some_dir/$_" } readdir(DIR);
    closedir DIR;
