由于 zsh 脚本，无法导出变量

2024-6-4 • tag-icon

我已经编写了一个脚本export-zsh来在 zsh 中设置新变量

$ cat export-zsh
#!/bin/bash
echo "export $@">> /root/.zshrc
source /root/.zshrc

运行它时会出现错误

$export-zsh "a=2"
/root/.zshrc: line 12: setopt: command not found
/root/.zshrc: line 33: bindkey: command not found
/root/.zshrc: line 36: bindkey: command not found
[...]
/root/.zshrc: line 42: modload: command not found
[...]

当我单独执行每个命令时，不会出现任何错误：

$ echo "export a=2">> /root/.zshrc; source /root/.zshrc
$ [ NO ERROR ]

当我运行时source ~/.zshrc，没有错误，所以我不认为它应该与我的 ~/.zshrc 内容直接相关，但我在下面给出它以确保无误。

您的脚本由 Bash 执行。.zshrc使用 Bash 读取您的脚本不起作用，但会导致所有 Zsh 特定内容出错。

您的脚本在其自己的子 shell 中运行。由于设置、环境变量等不会导出回调用 shell，因此脚本在这里不起作用。请改用函数并将其放入您的.zshrc：

export-zsh(){
    echo "export $@">> .zshrc
    source .zshrc
}
