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)
