问题描述

当前在我的终端中，每个shell提示符都类似于ComputerName: FooDir UserName$. UserName部分仅浪费了我宝贵的80列中的太多空间.有办法抑制它吗?

Currently in my Terminal, every shell prompt looks like ComputerName: FooDir UserName$. The UserName part simply wastes too much space out of my precious 80 columns. Is there a way to suppress it?

推荐答案

提示由环境变量PS1定义，您可以在.bash_profile中定义.

The prompt is defined by the environment variable PS1 which you can define in .bash_profile.

要对其进行编辑，请打开或创建(隐藏)文件.bash_profile:

To edit it, open or create the (hidden) file .bash_profile:

nano .bash_profile

并添加一行说明

export PS1=""

在引号之间，您可以插入所需的内容作为终端提示.您还可以在其中使用变量:

Between the quotation marks, you can insert what you would like as your terminal prompt. You can also use variables there:

• \d –日期
• \t –时间
• \h –主机名
• \# –命令号
• \u –用户名
• \W –当前目录(例如:桌面)
• \w –当前目录路径(例如:/Users/Admin/Desktop)

• \d – date
• \t – time
• \h – hostname
• \# – command number
• \u – username
• \W – current directory (e.g.: Desktop)
• \w – current directory path (e.g.: /Users/Admin/Desktop)

常见Linux发行版的默认提示符为\w $，在您的主目录或例如，其值为~ $. /Users $其他地方.还有一些网站(例如这)可以帮助您建立提示.

The default prompt for common Linux distributions would be \w $, which evaluates to ~ $ in your home directory or e.g. /Users $ somewhere else. There are also website (like this one) that can help you with building your prompt.

如果要删除UserName部分，则选择\h: \w$.

If you want to remove the UserName part, your choice would be \h: \w$.

进行更改后，请使用 Control + o ， Return ， Control + x .

Once you made your changes, save the file with Control+o, Return, Control+x.
