How to make a sound once a process is complete?
I have started a long process through a terminal. Is it possible to make the Ubuntu terminal make a sound once the process is complete? This way, I don’t need to keep checking, but will instead be notified through a sound.
Do you mean, open an application from terminal and when it finish, make a sound? Do you have an Ubuntu server or you mean GUI software?
yes exactly. For example i start a command line program, and once it exits and control is returned back to the terminal, a sound is made. I am currently using Ubuntu 12.10

Replace «make» with whatever long-running command you use.
spd-say ‘get back to work ‘. And comes pre-installed as well: releases.ubuntu.com/trusty/… , for blind people I suppose? And -w for infinite loops: while true; do spd-say -w ‘get back to work you lazy bum’; done .
There are at least three command line ways to accomplish this by putting the suiting command at the end of your script you may invoke for your lengthy process:
- The «classical» way to play a sound is to use beep. Beep will make a tone through the PC speaker. However this will not work in all cases (e.g. in my system PC speakers are completely disabled) You may have to remove pcspkr from /etc/modprobe/blacklist.conf and load the pcspkr kernel module:
sudo sed -i 's/blacklist pcspkr/#blacklist pcspkr/g' /etc/modprobe.d/blacklist.conf sudo modprobe pcspkr beep [optional parameters]
aplay /usr/share/sounds/alsa/Side_Right.wav
paplay /usr/share/sounds/freedesktop/stereo/complete.oga
We can use default sound files from /usr/share/sounds/ , or any other sound file we may have in a different location.
Just to have mentioned it, there is another nice way to achieve this by misusing espeak, which is installed by default in Ubuntu
#! /bin/bash c=10; while [ $c -ge 0 ]; do espeak $c; let c--; done; sleep 1 ## here lengthy code espeak "We are done with counting"
In Ubuntu >= 12.10 Orca uses speak-dispatcher. We can then install espeak, or alternatively use spd-say «Text» .
@Lucio: yeah, now that you say it. They switched to speak-dispatcher. If this works (it does not on my system) see edit for using spd-say .
According to this the \a character escapes ASCII code 7, which is the computer’s beep.
So echo $’\a’ works to make a beep sound on my local machine, even when it’s executed on a bash shell running on a computer I’m connected to via a terminal interface like PuTTY.
amazing! that’s the easiest and best solution (at least for me) because it does not require to install any 3rd-party apps and can even be typed/pasted in the middle of the process to be run after command prompt will take focus.
@Max $ followed by an expression in single quotes is treated in a special way by Bash. It is nonstandard and will not work in the standard UNIX Bourne shell. see stackoverflow.com/questions/13925879/what-does-n-mean-in-bash
this works for me on both macOS Terminal.app and iTerm2 locally and logged into a remote server on ssh. However, it does not work when I am in a screen session.
TL;DR
To play a sound after command finishes:
(where sn3 is sound number 3) put this in .bashrc :
Or read below for more options:
Different sound on error and success
Here is what I use for exactly what you ask for — with one difference: it not only plays a sound when the command finishes but it plays a different sound on success and on error. (But you can change it if you don’t like it.)
I have a Bash function called oks that I use at the end of long running commands:
It plays a sound and displays OK or ERROR (with error code) when the previous command finishes.
Source code
Here is that function with two helpers:
sound() < # plays sounds in sequence and waits for them to finish for s in $@; do paplay $s done >soundbg() < # plays all sounds at the same time in the background for s in $@; do # you may need to change 0 to 1 or something else: pacmd play-file $s 0 >/dev/null done > oks() < # like ok but with sounds s=$? sound_ok=/usr/share/sounds/ubuntu/stereo/dialog-information.ogg sound_error=/usr/share/sounds/ubuntu/stereo/dialog-warning.ogg if [[ $s = 0 ]]; then echo OK soundbg $sound_ok else echo ERROR: $s soundbg $sound_error fi >
Installation
You can put it in your ~/.bashrc directly or put it in some other file and then put this line in your ~/.bashrc:
Configuration
Change sound_ok and sound_error to some other sounds.
You can experiment with sound vs. soundbg and change sound_ok and sound_error to use sequences of many sounds that you like to get the result that you want.
Good sounds
To find some good sounds on your system you can try:
for i in /usr/share/sounds/*/stereo/*; do echo $i; paplay $i; sleep 1; done
Here are some sounds that I often use that are available on Ubuntu by default that are good for notifications — sn1 is loud and nice, sn2 is very loud and still pretty nice, sn3 is extremely loud and not so nice:
Again, you can change sound to soundbg if you want to play it in the background without waiting for the sound to finish (e.g. to not slow down your scripts when you play a lot of sounds).
Silent version
And just in case — here is the same function as oks but without sounds:
Usage
Of course in practice the commands are more like:
but I used ls so you could quickly see how it works.
You can use ok instead of oks for a silent version.
to print OK/ERROR but always play the same sound, etc.
Update
I put those functions on GitHub, see:
The source can be downloaded from:
Update 2
I added a soundloop function to the above repo. It plays a sound and can be interrupted by Ctrl+C (unlike a simple while true; do paplay file.ogg; done that one would expect to work but it doesn’t) as asked by shadi in the comments. It is implemented as:
soundloop() < set +m a=`date +%s` < paplay $1 & >2>/dev/null wait b=`date +%s` d=$(($b-$a)) [ $d -eq 0 ] && d=1 while :; do pacmd play-file $1 0 >/dev/null sleep $d done >
If you think it is complicated, please direct your complains to PulseAudio developers.
I tried to put this in a while true; do paplay . ; done so that the sound repeats until I hit Ctrl+C , but when I do, it doesn’t break. I can’t find any special options in man paplay to figure out how to get this to work. Any ideas?
Expanding on Michael Curries’s answer, you could make Bash print a BEL ( \a ) character through PROMPT_COMMAND :
Setting PROMPT_COMMAND that way will make Bash execute printf \\a at the end of each command, which will make the terminal play a sound (though as muru points out, simply triggering the redrawal of the prompt will make the terminal play the sound, i.e. the sound will be played each time a new prompt is drawn, for example even when just hitting ENTER ).
This is a terminal feature, so it might not work across all terminals; for example it doesn’t work in the console (but I’m sure it works in gnome-terminal and xterm ).
makes a noise sound. Simplest but annoying solution. 🙂
Look at the manual of speaker-test(1) for options to configure the noise signal.
If you do not mind installing sox, you can play Silicon Heaven Hymn:
sudo apt install sox while true; do play -q -v 100 -n synth .$(( $RANDOM % 51 ))1 sine $((200 + $RANDOM % 4000 )) &> /dev/null; done
If you do not mind to install espeak:
sudo apt install espeak espeak 'Johnny is marching home! Hurray!' espeak -v german 'Doch! Ich bin vertig!' espeak -x -v czech 'Běžela Magda kaňonem, srážela banány ramenem.'
This is not what you asked but you could use notification for that.
Replace the command given in the other answers with
notify-send "Process terminated" "Come back to the terminal, the task is over"
I went to add a shorthand to my .bashrc to do this, and I realised ubuntu already had one! ex: sleep 10; alert
Super simple answer:
Do it after a long command, emulated by sleep 2 here:
More details:
To make this easy to use, add this to the bottom of your ~/.bashrc file (create this file if it doesn’t exist). Or, if using Ubuntu, add it to your ~/.bash_aliases file instead (which file is imported by Ubuntu’s default ~/.bashrc file) like I do in my ~/.bash_aliases file here:
# Play sound; very useful to add to the end of a long cmd you want to be notified of when it completes! # Ex: `long_cmd; gs_sound_bell` will play a bell sound when `long_cmd` completes! alias gs_sound_bell="echo -e \"\a\"" # Even better, have a pop-up notification too! # Ex: `long_cmd; gs_alert` will play the sound above *and* pop up a notification when complete! # See more details & a screenshot of the popup on my answer here: # https://askubuntu.com/questions/277215/how-to-make-a-sound-once-a-process-is-complete/1213564#1213564 # For other popup window options, see my other answer here: # https://superuser.com/questions/31917/is-there-a-way-to-show-notification-from-bash-script-in-ubuntu/1310142#1310142 alias gs_alert="gs_sound_bell; alert \"task complete\""
Notice that my gs_alert alias calls alert , so you need that alias defined too. This alias is defined by default in Ubuntu. But, if your ~/.bashrc file doesn’t already have this near the top of it, then add it just above the code above. Again, these lines come default in your ~/.bashrc file in Ubuntu 18 or 20, for instance:
# Add an "alert" alias for long running commands. Use like so: # sleep 10; alert alias alert='notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal || echo error)" "$(history|tail -n1|sed -e '\''s/^\s*2\+\s*//;s/[;&|]\s*alert$//'\'')"'
Test it:
Close and re-open your terminal, or call . ~/.bashrc to re-«source» the file, then test it like this:
After 2 seconds you’ll hear the bell sound and see this pop up at the top of your screen:
If you ever forget what your alias contains, you can see what’s in each one by running this:
# See the definitions for ALL aliases you have defined! alias # See just the definitions for specific aliases. Ex: alias gs_sound_bell alias gs_alert alias alert
Use it:
# get alerted when `my_long_cmd` finishes! Ex: building software. my_long_cmd; gs_alert
Notes:
- The gs_ part at the beginning of each alias is my initials. I prepend my custom commands and aliases with this to make them easy to find: I can now just type gs_ at the terminal then press Tab Tab ( Tab twice) to see all my custom commands print out.

ffmpeg sine wave
For the minimalists out there, you can play a 1000 Hz sine for 5 seconds:
sudo apt-get install ffmpeg ffplay -f lavfi -i "sine=frequency=1000:duration=5" -autoexit -nodisp
or forever until you do Ctrl-C:
ffplay -f lavfi -i "sine=frequency=1000" -nodisp
Tested in Ubuntu 18.04, ffmpeg 3.4.6.
You can press Ctrl + g on your keyboard while on the terminal window that is running the command and when the command finishes it’ll beep. If you press it multiple times it will beep many times as well.
command && (say done ; echo done) || (echo error ; say error)
Example 1: echo alik && (say done ; echo done) || (echo error ; say error) will result in a done word.
Example 2: non_existing_command_error && (say done ; echo done) || (echo error ; say error) will result in an error word.
sudo apt-get install gnustep-gui-runtime
I created a simple and almost-native script that plays Sound and displays a Notification with a Given Message and Time for Ubuntu (Gist):
#!/bin/sh # https://gist.github.com/John-Almardeny/04fb95eeb969aa46f031457c7815b07d # Create a Notification With Sound with a Given Message and Time # The Downloaded Sound is from Notification Sounds https://notificationsounds.com/ MSSG="$1" TIME="$2" # install wget if not found if ! [ -x "$(command -v wget)" ]; then echo -e "INSTALLING WGET. \n\n" sudo apt-get install wget echo -e "\n\n" fi # install at package if not found if ! [ -x "$(command -v at)" ]; then echo -e "INSTALLING AT. \n\n" sudo apt-get install at echo -e "\n\n" fi # install sox if not found if ! [ -x "$(command -v sox)" ]; then echo -e "INSTALLING SOX. \n\n" sudo apt-get install sox sudo apt-get install sox libsox-fmt-all echo -e "\n\n" fi # download the noti sound if this is first time # add alias to the bashrc file if ! [ -f ~/noti/sound.mp3 ]; then echo -e "DOWNLOADING SOUND. \n\n" touch ~/noti/sound.mp3 | wget -O ~/noti/sound.mp3 "https://notificationsounds.com/wake-up-tones/rise-and-shine-342/download/mp3" sudo echo "alias noti=\"sh ~/noti/noti.sh\"" >> ~/.bashrc source ~/.bashrc echo -e "\n\n" fi # notify with the sound playing and particular given message and time echo "notify-send \""$MSSG\"" && play ~/noti/sound.mp3" | at $TIME
