why can *some* git commands not be run from within .git directory?

why can *some* git commands not be run from within .git directory?

[Robert P. J. Day]

  just noticed something i was unaware of -- some git commands can't
be run if i'm in the .git directory, while others can. for example,
if i "cd .git", commands like this work just fine:

  $ git show
  $ git branch
  $ git log

but others seem unwilling to determine the "working tree":

  $ git status
  fatal: This operation must be run in a work tree
  $

and:

  $ git stash list
  fatal: /usr/libexec/git-core/git-stash cannot be used without a working tree.
  $

what's the distinction between commands that can work this way, and
commands that can't?

p.s. i will refrain from pointing out the inconsistency in using the
phrases "work tree" and "working tree" to mean the same thing, when
there is a distinct "worktree" entity.

Once Git finds a .git directory, or determines it's in one, it doesn't
look "higher"; instead, it runs like it's in a bare clone. That means
any command that requires a work tree or an index generally won't
work. Of course, you can still tell Git where the work tree is and
then the commands work fine from the .git directory:

incom@Jael MINGW64 /c/Temp/example/.git (GIT_DIR!)
$ GIT_WORK_TREE=.. git status
On branch master
Your branch is up-to-date with 'origin/master'.

nothing to commit, working tree clean

No you won't, clearly.

  ah, thank you, that clarifies it.
