Disable annoying bell in Gnome Terminal, vim, xterm, etc...
We’ll hear it when we reach the end of a line, we’ll hear it when we hit tab to complete a word and there’s more than one choice, in about 2 minutes you won’t hear it anymore. It’s the simplest thing to do but we never look into it – because most of the time when the bell goes off we’re in the middle of something else.
