Play musical notes from octave of middle C

man beep | sed -e '1,/Note/d; /BUGS/,$d' | awk '{print $2}' | xargs -IX sudo beep -f X -l 500
Are there any creative pieces of music that can be created using beep and the shell? I'd love to hear it!

Nice! Using the manpage as a data store.

I'm so glad that you guys love it! :) I just saw beep being used on command line fu and next thing I know I got it from the repos and looking at the man page and the musical notes seemed like a fun thing to try out :D

Here's some fun: This will wait between MIN and MAX seconds, and make a randomly pitched beep that lasts between zero and 0.6 seconds. This is the kinda thing that drives sysadmins absolutely nuts while you're off at lunch. ;-) MIN=20; MAX=60;MOD=$(($MAX-$MIN)); while sleep $(( $RANDOM % $MOD + $MIN));do beep -f $(($RANDOM % 19960 + 40)) -l $(($RANDOM%600 ));done Note that ubuntu users (and others) may require root permissions in order to do this. See the beep manpage for ways to fix this.

On Ubuntu, the easy fix to make beep non-root executable is this: beep=$(whereis beep|awk '{print $2}');sudo chmod g+x $beep; sudo adduser $USER $(ls -l $beep|awk '{print $4}') This just makes beep executable by it's group, and then adds you to that group. On non-ubuntu systems, it's wise to make sure that the group is not "root", which could cause some security issues when you run this. Aside from that, it should work as is
