How to turn off bell in PengWin Bash WSL

The audible bell in bash can be really annoying espcially if you are like me and use filename completion ( Tab-Tab) a lot.

Here is how you turn it off. Edit the /etc/inputrc global resource file for bash, and disable audible bell. You just need to delete a single comment character on line 21 of the rc file. You will need to sudo as this file requires superuser permission.

sudo vi +21 /etc/inputrc

press i to switch to input mode, delete the # comment character at the start of the line. Press Esc to exit input mode, then type uppercase ZZ ( that's Shift-Z twice) to save and exit vi.

Line 21 of your rc file should now like like this.

# do not bell on tab-completion
set bell-style none  
# set bell-style visible

Exit your Bash terminal and restart the terminal and that annoying beep should be gone.

If you also use vi (it's great for quick fixes), you should also disable the audible bell. To do this, change to your home directory with the cd command and edit a (new) file called .vimrc to add a single line:

cd  
vi .vimrc  

Then add the following line (again, switch to input mode first by typing i), then add the following line:

set visualbell  

To exit, press Esc to exit the input mode, and type upper case Z twice to Save the file and quit.

As I am actively exploring WSL and PengWin and hitting any issues, I'll drop my solutions here. It might just help you, so feel free to mention me on twitter, and let me know how you get on. ;-)
