如何使当前目录成为git工作目录

Question

I've written multiple *.cpp files in the location ~/Code/CPLUS before I know the existence of git.

Now I want to use git for version control.

I created a folder ~/git_repo/ , and in this folder, I ran git init command. When I tried to run the command git add my_first_c.cpp under the path ~/Code/CPLUS , the following message appeared:

fatal: Not a git repository (or any of the parent directories): .git

Then I typed git init ~/git_repo/ under the path ~/Code/CPLUS , the same error still appeared when git status was typed.

If I type git init under the path ~/Code/CPLUS , the add and commit can be executed. The only problem is that .git is stored in ~/Code/CPLUS/ , while I'd like it be stored in ~/git_repo .

My question is how to make the folder ~/Code/CPLUS a working directory while the repo info is stored in ~/git_repo/ ? And my machine has no GUI.

Answer 1

您可以尝试从终端（或在〜/ .bashrc中）导出变量export GIT_WORK_TREE=~/git_repo/并export GIT_DIR=../Code/CPLUS ，以便Git使用它们。

Answer 2

Thanks @Alariva , the suggested solution indeed solved this question. With .git created in ~/git_repo/ , typing git --git-dir=/abs/path/to/repo/git_repo/.git add my_first_c.cpp works.

The solution comes from this post .
