Play sound on mac terminal

printf \\a and osascript -e beep play the default alert sound, but they are silent if the alert volume is set to zero. printf \\a is also silent if an audible bell is disabled.

You could also use afplay or say:

afplay /System/Library/Sounds/Funk.aiff
say done

There are more sound effect files in /System/Library/PrivateFrameworks/ScreenReader.framework/Versions/A/Resources/Sounds/.

The simplest way is the use a bell echo -e "\a"

Another way is to echo ^G. But you don't literally type the ^G. Instead, type ctrl+v, ctrl+g, which will appear as echo ^G.
