how to git clone with specific revision and depth=1

Question

I saw a following line in a manifest file in .repo. How can I do the same with the git command in manifest.xml? I'd like to know how to run 'git clone' with specific revision and depth=1.

<project clone-depth="1" groups="pdk-cw-fs,pdk-fs" name="repository name" path="repository path" revision="SHA1"/>

If revision is a branch( refs/heads/xxx ) or a tag( refs/tags/xxx ),

git clone $remote -b $revision --depth=1 --single-branch
#or
git fetch $remote $revision --depth=1 && git checkout FETCH_HEAD

If revision is a specific commit or a ref under other namepaces, not refs/tags/ or refs/heads/ ,

git fetch $remote $revision --depth=1 && git checkout FETCH_HEAD

Note that when revision is a specific commit at which no ref is pointing, git fetch would fail due to error: Server does not allow request for unadvertised object . The variables in git config or the hosting service config allow to fetch an unadvertised object:
