关掉终端铃声

在 Linux 控制台下（没有 X11），你可以使用一下命令:

setterm -blength 0

#alternatively you can change the frequency of the beep to a
#very low value:

setterm -bfreq 10

而在 X11 下面(不管是 KDE、Gnome、XFCE 或者……) 你可以:

xset b off


对每种 shell 操作
作为一种可能的选择，你可以直接关掉某种 shell 里的提示音。

对 Bash:

# has to go into /etc/inputrc or .inputrc
# It will not work in a .bashrc file!
set bell-style none



对 Tcsh:

# put this into your .tcshrc file

# just tab completion beep off:
set matchbeep = never
# any beep off:
set nobeep = 1
