Bell

• Want to turn off the bell / chime / buzzer / alarm? In Linux, one way to do this is
  xset b off
  To turn the volume down use 
  xset b 10
  where 10 indicates the volume should be 10% of the maximum. You'll want to put this command in your .bashrc or .cshrc file so that it's turned off whenever you login.
• You may also be able to do this in the /etc/inputrc file by including the line 
  set bell-style none
  though when I tried this without rebooting, it didn't work.
