I am executing every now and then some python scripts which take quite long to execute.

I execute them like this:
$ time python MyScript.py

How can I play a sound as soon as the execution of the script is done?

I use Ubuntu 10.10 (Gnome desktop).

Append any command that plays a sound; this could be as simple as

$ time mycommand; printf '7'

or as complex as

$ time mycommand && paplay itworked.ogg || paplay bombed.ogg

(Commands assume pulseaudio is installed; substitute your sound player, which will depend on your desktop environment.)

Just pick a sound on your hard drive, and put a command to play it right after the command you're waiting on; they'll happen sequentially:

$ time python MyScript.py; mplayer ~/ScriptDone.wav

(You can use any player, naturally). I have a script called alertdone that plays a tone and shows an libnotify alert when run; I use it for exactly this occasion:

$ time python MyScript.py; alertdone "Done timing"

It's really simple, so if you want to make your own you can base it on this (mine requires notify-more, mplayer, and ~/tones/alert_1.wav though):

#!/bin/bash
message=$1:-"Finished working"
notify-more -t 10000 -i /usr/share/icons/gnome/32x32/actions/insert-object.png "Process Finished" "$message"
mplayer ~/tones/alert_1.wav

time python MyScript.py; play /path/so/sound.ogg

play is a very basic (no UI) sound player from the sox Install sox http://bit.ly/software-small package. You can replace it by any other command-line-driven sound player.

spd-say

sleep 2; spd-say 'get back to work'

Infinite loop with -w if you need extra motivation:

sleep 2; while true; do spd-say -w 'get back to work'; done

Pre-installed on 14.04 via package speech-dispatcher: http://releases.ubuntu.com/trusty/ubuntu-14.04.4-desktop-amd64.manifest for blind people I suppose?

Also add a popup

This combo is a life saver:

b() ( spd-say 'done'; zenity --info --text "$(date);$(pwd)" & )

and then:

super-slow-command;b

If I'm somewhere in the room, I'll hear it and know that the long job is done.

Otherwise, I'll see the popup when I get back to my computer.

You can also make this happen automatically.

I will show you how in zsh, then add info about bash.

The essence looks like this:

preexec()

 starttime=$SECONDS


precmd()

 if ((SECONDS - starttime >= 5)); then
 aplay "sound.wav"
 # or printf "b", or notify-send, or whatever
 fi

You can also make it only do it if the program was Python, e.g.

preexec()

 starttime=$SECONDS
 case $3 in python*)
 command_is_python=true;;
 *)
 command_is_python=false;;
 esac


precmd()

 if $command_is_python && ((SECONDS - starttime >= 5)); then
 aplay "sound.wav"
 # or printf "b", or notify-send, or whatever
 fi

In bash, the best way is to download preexec.bash.txt and source it (e.g. . ~/preexec.bash.txt at the top of your ~/.bashrc, then the above (or something close to it) should work. (Not sure about the $3 bit to check if the command is Python.)

If you're using GNOME Terminal, I would also point you to Flashing GNOME Terminal. It's a patch I wrote that makes the terminal blink when a command is done, so you can Alt-Tab to something else, then it lets you know when it's done.

Personally, I use my-script && notify-send "done". This sends a desktop notification, which on Linux Mint looks like this:
