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.

  • Can you explain further what do you mean with process complete? – Lucio Apr 2 '13 at 18:21

    @Lucio control is returned back to the terminal – Goaler444 Apr 2 '13 at 18:23

    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? – Lucio Apr 2 '13 at 18:24

    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 – Goaler444 Apr 2 '13 at 18:31

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:

  1. The "classical" way to play a sound is to use beep Install beep through the PC speakers. However this will not work in all cases (e.g. in my system PC speakers are completely disabled) and you will need to remove pscpkr 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]
    
  2. We can also play any sound file in wav format using aplay (installed by default):

    aplay /usr/share/sounds/alsa/Side_Right.wav
    
  3. Another way is to use the pulseaudio command line interface to enable playback of any sound files your system (in libsndfile) recognizes on the default audio output:

     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 <= 12.04. See, or rather hear the following example:

#! /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 Install espeak, or alternatively use spd-say "Text".

    @Takkat I'm using Ubuntu 12.10 and espeak is currently not installed. – Lucio Apr 2 '13 at 20:55
  • @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. – Takkat Apr 2 '13 at 21:07
  • @Takkat The spd-say utility is installed by default and it works on my system. – Lucio Apr 2 '13 at 21:09
  • Also take a look to this Q/A – c0rp Apr 22 '15 at 5:32

    I had good success with paplay /usr/share/sounds/freedesktop/stereo/complete.oga – Nicholas DiPiazza Jan 11 '17 at 19:27

I use

make; spd-say done

Replace "make" with whatever long-running command you use.

TL;DR

To play a sound after command finishes:

long-running-command; sn3

(where sn3 is sound number 3) put this in .bashrc:

sound() {
  # plays sounds in sequence and waits for them to finish
  for s in $@; do
    paplay $s
  done
}
sn1() {
  sound /usr/share/sounds/ubuntu/stereo/dialog-information.ogg
}
sn2() {
  sound /usr/share/sounds/freedesktop/stereo/complete.oga
}
sn3() {
  sound /usr/share/sounds/freedesktop/stereo/suspend-error.oga
}

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:

make && make test && make install; oks

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:

. ~/path/to/file/with/function

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:

sn1() {
  sound /usr/share/sounds/ubuntu/stereo/dialog-information.ogg
}
sn2() {
  sound /usr/share/sounds/freedesktop/stereo/complete.oga
}
sn3() {
  sound /usr/share/sounds/freedesktop/stereo/suspend-error.oga
}

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:

ok() {
  # prints OK or ERROR and exit status of previous command
  s=$?
  if [[ $s = 0 ]]; then
    echo OK
  else
    echo ERROR: $s
  fi
}

Usage

Here is how you use it:

Example with success:

ls / && ls /bin && ls /usr; oks

example with error:

ls / && ls /bim && ls /usr; oks

Of course in practice the commands are more like:

make && make test && make install; oks

but I used ls so you could quickly see how it works.

You can use ok instead of oks for a silent version.

Or you can use e.g.:

ls / && ls /bim && ls /usr; ok; sn1

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? – shadi Sep 24 '16 at 18:23
  • @shadi See my updated answer for a solution with a sound that repeats until you hit Ctrl+C. – rsp Jan 18 '17 at 21:39

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. – hlopetz Jul 28 '16 at 8:57

    the sound of this character is disabled in most modern terminals by default – Blauhirn Mar 24 '18 at 0:05

Expanding on Michael Curries's answer, you could make Bash print a BEL (\a) character through PROMPT_COMMAND:

PROMPT_COMMAND='printf \\a'

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-terminaland xterm).

The command

 speaker-test

makes a noise sound. Simplest but annoying solution. :-)

Look at the manual of speaker-test(1) for options to configure the noise signal.

2

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"
1
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

How To Use?

First Run - Setting Up:

  1. Create a new Directory at your home and call it noti

    mkdir ~/noti
    
  2. Download noti.sh and extract it to the above noti dir.

  3. Open Terminal and Change Directory to noti

    cd ~/noti
    
  4. Make noti.sh executable by issuing:

    sudo chmod +x noti.sh
    
  5. Run a Test like this:

    sh ~/noti/noti.sh "Test" "now"
    

Examples

noti "Hello From Noti" "now +1 minute"
noti "Hello From Noti" "now +5 minutes"
noti "Hello From Noti" "now + 1 hour"
noti "Hello From Noti" "now + 2 days"
noti "Hello From Noti" "4 PM + 2 days"
noti "Hello From Noti" "now + 3 weeks"
noti "Hello From Noti" "now + 4 months"
noti "Hello From Noti" "4:00 PM"
noti "Hello From Noti" "2:30 AM tomorrow"
noti "Hello From Noti" "2:30 PM Fri"
noti "Hello From Noti" "2:30 PM 25.07.18"

For Notifying The Finish of Process (example)

sudo apt-get update; noti "Done" "now"

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

More information at: https://stackoverflow.com/questions/5109038/linux-sine-wave-audio-generator/57610684#57610684

Tested in Ubuntu 18.04, ffmpeg 3.4.6.
