向 ZSH 中的 PATH 变量添加新条目 [英] Adding a new entry to the PATH variable in ZSH
问题描述
我正在使用 zsh 并且我正在尝试向 PATH
变量添加一个新条目 (/home/david/pear/bin
) 但我没有不知道怎么做.
I'm using zsh and I'm trying to add a new entry (/home/david/pear/bin
) to the PATH
variable but I don't know how.
最让我困惑的是没有一个引用我的 ~/.zshrc
文件中的 PATH
变量,但执行 echo $PATH
返回:
The thing that confuses me the most is that there's not a single
reference to a PATH
variable in my ~/.zshrc
file, but doing echo $PATH
returns:
/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
因此在某处设置了 PATH
变量.
So a PATH
variable is being set somewhere.
推荐答案
这里,在.zshrc
中加入这一行:
Here, add this line to .zshrc
:
export PATH=/home/david/pear/bin:$PATH
编辑:这确实有效,但是下面的ony 的答案更好,因为它需要ZSH 为诸如 $PATH
之类的变量提供的结构化接口的优势.这种方法是 bash
的标准,但据我所知,当 ZSH 提供更好的替代方案时,没有理由使用它.
EDIT: This does work, but ony's answer below is better, as it takes advantage of the structured interface ZSH provides for variables like $PATH
. This approach is standard for bash
, but as far as I know, there is no reason to use it when ZSH provides better alternatives.
