打印\a并不总是为我工作(MBA, 10.7.4)。我用这个代替:

say "beep"

printf "\a"

如果你看man printf，它会给你一个转义字符列表，包括\a:

\a      Write a <bell> character.

如果你需要什么，听起来就像“important”

你可以使用

tput bel && sleep 0.33s && tput bel && sleep 0.33s && tput bel && sleep 0.33s && tput bel && sleep 0.33s && tput bel && sleep 0.33s && tput bel && sleep 0.33s && tput bel && sleep 0.33s && tput bel && sleep 0.33s && tput bel && sleep 0.33s && tput bel && sleep 0.33s

:)

终端类型:

echo -e "\a"

e参数告诉echo处理转义字符。由于\n是新的行字符，\a是钟形字符(与Ctrl+G相同)。

告诉应用程序“系统事件”哔哔声
