How to play a sound after a command is finished

Tue, 16 May 2017 23:59:39 +0000

Install espeak:

macOS:

brew install espeak

Ubuntu Linux:

sudo apt-get install espeak

Run a (time-consuming) command at the UNIX command-line and play a sound when it is finished so you don't need to wait for it to finish or constantly check back:

bash$ sleep 10s && espeak 'Done!'
