I'm just a lurker so my opinion doesn't count. for much.
Certainly I don't expect everyone to be a programmer in order to be able
to shuffle their playlist, but perhaps an example needs to be added to
the sort man-page stating how easy is to accomplish with tools that are
likely already installed on your system (specifically, "awk" to add a
pseudorandom key to a line and "cut" to remove it):
find /music -name '*ogg' -type f |
awk 'BEGIN{srand()}{printf "%06d%s\n", rand()*1000000, $0}' |
sort |
cut -b 7- > /music/randomized_oggfiles.m3u
Remove srand() if you prefer more deterministic behavior. Standard
disclaimers about using pseudorandom numbers for anything important
apply.
As to adding a random function to sort that would keep like-keys
together, perhaps that can be achieved by abusing the locales and
collate function that does unexpected things for many users anyway? I'm
only half serious when I say that, but LANG=(something other than C) has
caused so many users so much grief already that LANG=random couldn't be
any worse.
Apologies for the noise on the list, but I hope you got a chuckle from
LANG=random anyway. I'll go back to lurking now.
