bash中的[[$-= * i *]]是什么意思?
我正在安装 liquidprompt ，他们在文档中要求您添加 [[$-= * i *]]&&来源〜/liquidprompt/liquidprompt 在您的 .bashrc 中.
I'm installing liquidprompt and in the documentation they ask you to add [[ $- = *i* ]] && source ~/liquidprompt/liquidprompt in your .bashrc .
我试图理解该系列的第一部分，但是对于像我这样的bash菜鸟来说，这很难.如果有人有一个不错的文档或答案...
I am trying to understand the first part of the line but it's hard for a noob in bash like me. If anyone has a nice doc or the answer...
$-包含当前的shell选项.
$- contains the current shell options.
在 [[... ...]] 中，如果未引用，则将 = 的右侧解释为模式.因此， * i * 表示 i 可能在任何内容之前或之后.
In [[ ... ]], the right hand side of a = is interpreted as a pattern if not quoted. Therefore, *i* means i possibly preceded or followed by anything.
换句话说，它将检查是否存在 i 选项，即当前shell是否是交互式的.
In other words, it checks wheter the i option is present, i.e. whether the current shell is interactive.
