zsh 的一个问题

[hongfeiyu]

设置"%(!.%{%F{yellow}%}.)$USER@%m"里的(!.%{%F{yellow}%}.)
是什么意思啊
？？？

这么多次点击居然一个回复都没有
难道我问的这个太偏了吗 2333333
类似于 Bash 的 PS1 设置
而 zsh 是这样的 _(:з」∠)_

感觉是一个字符串格式化的意思，应该是以某种格式，加字体颜色为黄色输出的意思。

@neoblackcap 我猜是如果是 root 用户的话就显示闪电的标志。。。

来自官方 Manual 的解释

%(x.true-text.false-text)

Specifies a ternary expression. The character following the x is arbitrary; the same character is used to separate the text for the ‘ true ’ result from that for the ‘ false ’ result. This separator may not appear in the true-text, except as part of a %-escape sequence. A ‘)’ may appear in the false-text as ‘%)’. true-text and false-text may both contain arbitrarily-nested escape sequences, including further ternary expressions.

The left parenthesis may be preceded or followed by a positive integer n, which defaults to zero. A negative integer will be multiplied by -1, except as noted below for ‘ l ’. The test character x may be any of the following:

!
True if the shell is running with privileges.

意思就是说，如果是 root 就用黄色。
