executing git from a non git directory

executing git from a non git directory

[Patrick Aljord]

Hey all,

I have my git directory that is in /path/to/my_git_dir

I would like to check it from another direcory, I tried the following command:

$ git --git-dir=/path/to/my_git_dir status

and

$ GIT_DIR='/path/to/my_git_dir' && git status

but in both cases I get this error:
fatal: Not a git repository: '/path/to/my_git_dir'

yet when I do "$ cd /path/to/my_git_dir && git status" I do get the results.

Any idea what I'm doing wrong or if there's a way to check a git dir
from a non git dir?

thanx in advance

Pat

These are actually the same two commands.  The --git-dir option
just means "set GIT_DIR before calling the real command".

However, there are two problems here...

Right.  That's problem number 1.  /path/to/my_git_dir is probably
not actually your Git repository.  The git repository is actually in
".git", so you really need to use:

  $ git --git-dir=/path/to/my_git_dir/.git status

However, problem number 2 is that status requires a working
directory.  Setting GIT_DIR explicitly like this tells git that
you don't have a working directory present.  So status won't work.

That's what you have to do if you want to run git-status.  Or use
a subshell as that won't change your current working directory:

  $ (cd /path/to/my_git_dir && git status)

A git dir is the location where all of the repository information is
stored; it is called '.git' for a directory with a working tree. Is
/path/to/my_git_dir really a git dir, or is it a working directory that
has a '.git' inside it?

If the latter, then you need to specify the .git directory. However,
running 'git-status' won't make any sense then, since you won't be in
the correct working tree (so of course it will look like files have been
removed).

You could do something like "git --dir /path/to/my_git_dir/.git branch"
and it would at least produce sensible results.

Right. That's the way you have to do it in the case of 'status', since
you need your current working directory to be in the right place.

If you are running a very recent git, you can now try:

  git --work-tree=/path/to/my_git_dir --git-dir=/path/to/my_git_dir/.git status

which is what you actually want.

ok, I'm going to try that, thanx.
