Productivity Hack of a day:
If you repeat builds that take time , copying files, partitions...
just add c_beep
after long running command!
long running command ; c_beep
Define c_beep
as alias or function or just file in PATH:
alias c_beep='sox -n -r 44100 -c 2 /tmp/c_beep.wav synth 2 sine 440 && play /tmp/c_beep.wav'
