Why are you calling git rev-parse --git-dir 2> /dev/null; ?

Why are you calling git rev-parse --git-dir 2> /dev/null; ?

Regarding questions above,

This checks for .git in current directory only.

[ -d .git ]

If you are in a subfolder it won't work. But rev-parse will work.

cd my-repo
cd docs
git rev-parse --git-dir
# Success! Output:
# /Users/mcurrin/repos/my-repo/.git

# Test the failure case.
cd ~
git rev-parse --git-dir
# Output
fatal: not a git repository (or any of the parent directories): .git

The 2> /dev/null bit hides the stderr on an error.

I don't think you even need the --git-dir flag since git rev-parse alone will return success but not text if in a git repo, or error and error message if not.

@MichaelCurrin Thanks for the explanation
