Tell me what will happen if a folder with a git-repository is added to another git-repository?

 folder structure:
 Level1 /
     .git
     Level2 /
         .git
         Level3
  • four
    What I do not know, but I suppose that this should be done through a submodule - andreymal
  • there will be a directory with a repository in the working copy of the repository. and you, apparently, were expecting something special. - aleksandr barakin

depending on what is meant by the word "add."

if it is intended to copy / create files / directories, then the git status command executed in the “top” directory will show the untracked Level1/Level2/Level3 (if I correctly understood that Level3 is a file, not a directory). all other files / directories will not be (by default) shown as untracked because they (from the point of view of the git program) are either “empty” or their names begin with a dot.

if the word “add” implies git add Level1/.git , then you will immediately get an error:

error: Invalid path 'Level1 / .git / HEAD'
error: unable to add Level1 / .git / HEAD to index
fatal: adding files failed

developers have come up with such a protective tool: to give an error when trying to add a file to the repository with the name HEAD , located in a directory named .git .

By the way, the same applies to the .git/config , .git/description , .git/hooks/* and .git/info/* files.

so if you really need to add one repository to another, it’s better to use the “ready” submodule mechanism.
