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

Printf“\a”也适用于终端，并将播放设置的警报声音。

macOS中没有“硬件哔哔声”。

The functionality you're thinking of is an artifact of very old (pre-1990s) IBM PC-compatible hardware. Before most computers had sound cards, most machines had a small speaker or piezo buzzer connected to one of the channels of a timer chip. This could be used to generate simple tones or beeps. Even after many computers integrated sound cards, it remained common for quite some time for computers to route this output to a separate internal speaker. More recently, many computers, especially laptops, have integrated this functionality into the onboard sound card.

(如果你对PC扬声器接口工作原理的技术细节感到好奇，这里有更多细节。)

这种硬件在苹果电脑中从未存在过。唯一可用的音频输出是通过声卡，macOS中唯一的系统哔哔声是用户的警报声。

确实，下面这段很有效果，也很有旋律:

say -v Bells "dong dong dong"

[更新]不幸的是bell不再包含在最新的OS x中。

say -v Victoria Do your homework!

使用以下方法探索声音:

say -v \?

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.

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
