readdir - get a directory from a directory handle




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