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;

[planetscape]: hello, Corion
[Corion]: Hi planetscape!
[stevieb]: Corion I like the groundbreaking ones (guitar players). I have the ability to pick up on sounds that are groundbreaking or specific to a person, thanks to my years of doing recording/mixing/ sampling (hip-hop mind you, but years of it...
[stevieb]: ...has honed in my skills of recognizing sound
[stevieb]: All of the early members are coming out of the woodwork today :) Hey, planetscape
[Corion]: This cover version had so much promise but the singing is underwhelming :-/
[stevieb]: erix Thanks! I dislike remakes of songs usually, but my favourite remix of guitar/weeps is Jeff Healey. I'll take a listen to yours
[planetscape]: hi stevieb!
[stonecolddevin]: also hi Corion
[Corion]: stevieb: Yeah, but I don't follow guitar players enough... I never got Prince and I don't think I could recognize his play style. I can recognize Santana and Nile Rodgers, but that's about it, and not really deep knowledge I think ;)
