如何关闭终端中的回声? [英] How do I turn off echo in a terminal?

问题描述

我正在编写一个 Bourne shell 脚本并输入如下密码:

I'm writing a Bourne shell script and have a password input like this:

echo -n 'Password: '
read password

显然，我不希望密码被回显到终端，所以我想在读取期间关闭回显.我知道使用 stty 可以做到这一点，但我会在阅读手册页的同时为了社区的利益提出这个问题.;)

Obviously, I don't want the password being echoed to the terminal, so I want to turn off echo for the duration of the read. I know there's way to do this with stty, but I'll ask the question for the benefit of the community whilst I go read the manpage. ;)

推荐答案

stty_orig=`stty -g`
stty -echo
echo 'hidden section'
stty $stty_orig
