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.

要了解更多选项，请听并选择

ls /System/Library/Sounds/ | awk '{print $1}' | while read sound; do printf "using $sound...\n"; afplay /System/Library/Sounds/$voice; sleep 0.5; done

ls /System/Library/PrivateFrameworks/ScreenReader.framework/Versions/A/Resources/Sounds/ | awk '{print $1}' | while read sound; do printf "using $voice...\n"; afplay /System/Library/PrivateFrameworks/ScreenReader.framework/Versions/A/Resources/Sounds/$sound; sleep 0.5; done

在MacOS X上，必须激活“声音警告”选项(终端/首选项)才能发出声音。

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

在bash中写入echo ^G。要创建^G，按ctrl+v，然后按ctrl+ G。

这将循环所有的声音(在约塞米蒂工作):

say -v '?' | awk '{print $1}' | while read voice; do printf "using $voice...\n"; say -v $voice "hello, this is me using the $voice voice"; sleep 1; done
