Git command to see where is the active GIT_DIR

Since the git command can be run from any subdirectory of the repo, or even from outside the directory hierarchy of the repo, I'm looking for a git command that'll show me the location of the repo. Essentially, parent directory of the repo's .git/ directory.

For example, if I have a directory structure as follows, I want the output of the command to be /Users/gurjeet/dev/project_repo/, for all the commands shown after the sample directory tree.

/Users/gurjeet/
├── some_directory/
└── dev/
    └── project_repo/
        ├── .git/
        └── src/

$ cd /Users/gurjeet/dev/project_repo
$ git --where-is-.git

$ cd /Users/gurjeet/dev/project_repo/src
$ git --where-is-.git

$ cd /Users/gurjeet/dev/
$ export GIT_DIR='/Users/gurjeet/dev/project_repo/src'
$ git --where-is-.git

$ cd /Users/gurjeet/dev/
$ export GIT_DIR='/Users/gurjeet/dev/project_repo/src'
$ git --where-is-.git

$ cd /tmp
$ export GIT_DIR='/Users/gurjeet/dev/project_repo/src'
$ git --where-is-.git

I believe what I was looking for is provided by git rev-parse --absolute-git-dir, or more accurately by the following command:

$ dirname $(GIT_DIR=~/dev/POSTGRES/.git git rev-parse --absolute-git-dir)

A few sample runs:

$ cd ~/dev/Q.HT/public/quote_of_the_day
$ dirname $(GIT_DIR=~/dev/POSTGRES/.git git rev-parse --absolute-git-dir)

/Users/gurjeet/dev/POSTGRES

$ cd ../../../POSTGRES/
$ dirname  $(GIT_DIR=~/dev/POSTGRES/.git git rev-parse --absolute-git-dir)

/Users/gurjeet/dev/POSTGRES

$ cd src
$ dirname  $(GIT_DIR=~/dev/POSTGRES/.git git rev-parse --absolute-git-dir)

/Users/gurjeet/dev/POSTGRES

Some Google foo lead me to Get the path where git alias was run from, which lead me to read git rev-parse --help, which had all the info I needed.
