克隆到相同的git目录是否安全

Question

For example, first there is no test directory, I git clone :

`git clone git@github.com:test/test.git test`

Then after some push/pull, I do it again:

`git clone git@github.com:test/test.git test`

Will the second clone damage the local test repo?

REASON:

I clone in a one-time script, which is supposed to run one time, ideally. But if it fails, or another reason, it might be run multiple times, so clone will be run multiple times too. If it's not ok, I will do an rm -rf test first.

Answer 1

As we can read in the git docs:

Clones a repository into a newly created directory

and

Cloning into an existing directory is only allowed if the directory is empty

In your case, cloning into an already cloned directory just won't work.

In your script you can handle/test the return code of git command and perform proper actions if git clone fails or not.

Replying to your question: yes, it's safe to run git clone multiple time. The repository won't be damaged.
