To use the functions first source it in Bash or in
Then you can use:
sn1 sn2 sn3 ok oks
For example to hear when a long-running command finishes and to hear a different sound on success and on failure:
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.
I posted those functions in the following answer on Ask Ubuntu:
They should work on any Linux distro after changing the paths to sounds.
To find good sounds on your system try:
for i in /usr/share/sounds/*/stereo/*; do echo $i; paplay $i; sleep 1; done
