Question:

There is a git repository in my LAN. I try to query Git to list all the HEAD references in the following way:

<strong>Method 1</strong>

<em>Command</em>

git ls-remote -h username@{ip-address}:/path/to/repo

<em>Output</em>

f0467f266dee55cd32f2ca6fa819814f367db899 HEAD

<strong>Method 2</strong>

<em>Command</em>

git ls-remote username@{ip-address}:/path/to/repo HEAD

<em>Output</em>

f0467f266dee55cd32f2ca6fa819814f367db899 HEAD

<strong>Method 3</strong>

<em>Command</em>

git ls-remote -h username@{ip-address}:/path/to/repo HEAD

When using the above command, the head reference which was listed in the above two methods is not listed.

Any idea on this?

I suspect this is because HEAD is a special kind of refs, it's not a head of a branch, it doesn't reside in refs/heads/ namespace. So when you ask git to list refs with both -h and HEAD git sees a contradiction and doesn't list any refs.
