我在.zshrc中使用以下提示:
I use the following prompt in .zshrc:
PROMPT="%{$fg[magenta]%}%n%{$reset_color%}@%{$fg[blue]%}%m %{$fg[yellow]%}%1~ %{$reset_color%}%# "打开终端时,我会看到以下提示:
When I open terminal I see this prompt:
zoltan@zoltan-Macbook-Pro ~ %是否可以在主机名中添加文本"zoltan"?我想使它看起来像这样:
Is it possible to drop the text "zoltan" in the hostname? I would like to make it look like this:
zoltan@Macbook-Pro ~ %任何建议将不胜感激.谢谢!
Any suggestion would be greatly appreciated. Thank you!
推荐答案有点麻烦,但是您可以假装%m是参数,并使用参数扩展从主机名中剥离zoltan:
It's a bit of a mess, but you can pretend the %m is a parameter and use parameter expansion to strip the zoltan from the host name:
PROMPT="...${${(%):-%m}#1} ..."一些解释.首先,创建一个实际上没有参数名称的参数"扩展.它只是将您提供的文本用作值":
A little explanation. First, you create a "parameter" expansion that doesn't actually have a parameter name; it just uses the text you provide as the "value":
${:-%m}下一步,添加%扩展标志,以便处理该值中找到的所有提示转义符.
Next, add the % expansion flag so that any prompt escapes found in the value are processed.
${(%):-%m}最后,接下来是使用#运算符从字符串中删除前缀的最终扩展:
Finally, next it in a final expansion that uses the # operator to remove a prefix from the string:
${${(%):-%m}#zoltan-}您可以通过逐个构建一点来驯服您的提示(并使用zsh的提示转义符来处理颜色变化,而不是显式地嵌入终端控制序列).
You can tame your prompt a bit by building up piece by piece (and use zsh's prompt escapes to handle the color changes, rather than embedding terminal control sequences explicitly).
PROMPT="%F{magenta}%n%f" # Magenta user name PROMPT+="@" PROMPT+="%F{blue}${${(%):-%m}#zoltan-}%f" # Blue host name, minus zoltan PROMPT+=" " PROMPT+="%F{yellow}%1~ %f" # Yellow working directory PROMPT+=" %# "更多推荐
