如果您想要一个临时的解决方案（因为您正在讨论屏幕播放），您可以设置您的PS1变量来更改提示符。
例如，如果您希望提示符为：

$

然后在终端上设置PS1变量如下：

export PS1='$ '

同样，您可以将其设置为您希望的任何提示符。如果要显示路径，请将其设置为：

export PS1='\w '

对于一个永久的解决方案，您可以在shell配置脚本中设置它，如果您使用bash作为shell，该脚本是您的~/.bashrc文件。

很多答案只是建议paste this PS1='\w....... '没有告诉变量是什么，基本上我们只需要知道3个变量; \u = username，\h = hostname，\w = current directory，则例如

PS1='\u@\h:\w \$ '

将成为

john@mypc:/home/dir $

这里是完整的列表

如果你经常想暂时隐藏终端信息，你可以在.bashrc中创建一个bash别名：

# hti - hide terminal info
alias hti='clear && export PS1="$ "'

并改用别名：

$ hti

要获取终端信息，请执行以下操作（您也可以为此创建别名）：

exec "$BASH"
