This was driving me nuts for ages – I couldn’t work out how to turn off that annoying beep you got whenever an auto-completion had multiple or no hits. Anyway, it’s a ReadLine configuration (so it’ll apply to any shell using ReadLone) – edit (or create) .inputrc in your home directory, and insert the following line:
set bell-style off
Finally – peace!

go into the window-settings menu option under ‘terminal’
select ’emulation’.
uncheck ‘audible beep’
check ‘visual beep’
click use settings as default
😉
Well sure, if you want to get all ‘easy to use’ on me, that might work too…
THANKS !!!!!
Really hated this ‘beep’ of the terminal.
Argh !
And yes, peace at last 🙂
Thanks again.
