Disable printing of control characters in your terminal

To disable the printing of ^C characters when you press CTRL+C in your terminal, you can set the following terminal line setting.

Copystty -echoctl

Copy~$ echo hello world
~$ 

If you want to have the control characters printed in your terminal again, type the same command without the minus sign

Copystty echoctl

Copy~$ echo hello world^C
~$ ^C

Add it to your .bashrc, .bash_aliases, or .profile to make it persistent.
