Getting Rid of the Terminal Beep:My terminal was making an annoying beeping (more like a swoosh beep, actually) every time it couldn't match a tab completion. I like to listen to music while I work, so this was really driving me crazy. All I needed to do to stop it was to run:
$ echo 'set bell-style none' >> ~/.inputrcwhich appends 'set bell-style none' to the .inputrc file in my home directory. .inputrc didn't exist in my home directory (I checked before running the command), so running this command created it.
