Mac .zshrc 写入环境变量时被覆盖了如何恢复？

Question

题目描述

错误的使用了写入命令

export GOPATH=$HOME/go > .zshrc

导致我的.zshrc文件空了，不过我没有执行 source .zshrc，但是打开其他的终端我的命令已经失效了

期待的结果

恢复我的.zshrc

Answer 1

貌似无法恢复，你这样直接覆盖了。

至于source .zshrc仅仅是是否使当前.zshrc直接生效，并不会有啥影响。

你可以在其他未关闭的终端echo $PATH 看一下历史的路径

Answer 2

vi ~/.zshrc, (不要sudo）

Swap file "~/.zshrc.swp" already exists!
[O]pen Read-Only, (E)dit anyway, (R)ecover, (D)elete it, (Q)uit, (A)bort:

选择：(R)ecover 恢复

或者看下 ~/.zshrc.swp 文件里面内容还在不在

Answer 3

在你还没有关闭的终端，执行env
抢救被你删除的环境变量，如http_proxy,PATH,Conda等等
