onhold is a command-line utility that allows you to play music while a long job completes.

ding is command-line utility that will play a sound after a long job completes.

Both utilities will take data that is piped into their standard inputs and pipe it to standard output. That is to say that data piped into onhold and ding will be piped right back out.

$ echo "Hello!" | onhold
Hello!

As a result, you can build pipelines with onhold and ding.

For example, you can download an ISO with http, visualize the progress with pv, play music with onhold while writing to /dev/null, and when it's finished, play a sound with ding.

$ export URL="http://releases.ubuntu.com/releases/21.04/ubuntu-21.04-desktop-amd64.iso"
$ http "$URL" | pv | onhold | ding > /dev/null

This project uses play_sounds, a wrapper over playsound and boombox.

You can either set the $ONHOLD environment variable to the song you'd like to play, or supply the song with the -s flag.

$ export ONHOLD="~/Music/song.mp3"
$ pv /dev/zero | onhold > /dev/null

This allows you to set $ONHOLD in your ~/.bashrc.

You can also specify it with a flag.

$ pv /dev/zero | onhold -s song.mp3 > /dev/null

onhold comes with a default song that will play if neither $ONHOLD or -s are set. You can use the -w flag to show warnings if $ONHOLD or -s are not set.

$ echo "Hello!" | onhold
Hello!

You can either set the $DING environment variable to the sound you'd like to play, or supply the sound with the -s flag.

# You can run ding after a command or as part of a pipeline
$ export DING="~/Music/ding.mp3"
$ sleep 5; ding
$ echo "Hello!" | ding
Hello!

This allows you to set $DING in your ~/.bashrc.

You can also specify it with a flag.

$ echo "Hello!" | ding -s ding.mp3
Hello!

ding comes with a default sound that will play if neither $DING or -s are set. You can use the -w flag to show warnings if $DING or -s are not set.

$ echo "Hello!" | ding
Hello!

You can install ding by itself. Future versions of onhold will not ship with ding. Click here to visit ding's project page with installation instructions.
