Audible alarm from Unix shell script

Having your script print a ctrl-G (^G) should make your PuTTY terminal beep.

You can adjust your PuTTY settings (category Terminal -> Bell) to change how the beep works for you.  I found the "default system alert sound" to be rather quiet; "Beep using the PC speaker" was a little more noticeable, but you could also set a custom sound.

To have your script do "echo ^G", you may need to type "echo <ctrl>-V<ctrl>-G".

Doesn't seem to work.  The UNIX environment here perhaps doesn't support this.

What unix OS is it?  (uname -a)

What happens at the unix prompt if you just type ctrl-G and hit return?

AIX and 'ctrl-G' not found

Are you typing "ctrl-G" or are you using the Ctrl key and the G key simultaneously?  The latter is what you want -- just hitting the Ctrl and G keys simultaneously.
As a control character, ctrl-G (or ^G) should make a noise, but not show up as an entered command.

Not sure about AIX, but on linux if you pipe random data to the audio device it gives quite an alarm.

echo "asldfjal;sdfja;lsdfjl;askdfj;alkfdjl;akfdj" > /dev/audio

echo "\a"
or
echo \\a

Works in my Putty session from Windows Vista to AIX with "Terminal" -> "Bell" -> "Make default system alert sound" and "Terminal" -> "Bell" -> "Beep using the PC speaker"
