github - get git hash for commit with specific tag without cloning or pulling

Question

I wish to get the git hash for a specific tag. For now what I do on the job is: ``` git clone GITHUB_URL git checkout TAG cd REPO_NAME export GIT_HASH=$(git log --pretty=format:%h -1) ``` Is there any chance I can get this without cloning or pulling or checking out?

Accepted Answer

so I started out with what @hvd said:

```
git ls-remote REPOLINK TAG
```

but that gave me only the tag hash, and I want the commit hash.

so I went back to:

```
git ls-remote REPOLINK 
```

and decided to grep for the tag:

```
git ls-remote REPOLINK | grep TAG
```

so now I have 2 rows, the first with the tag hash, and the 2nd with commit hash. so first we need to take just the second line:

```
git ls-remote REPOLINK | grep TAG | sed -n 2p
```

and we now have:

```
HASH TAG
```

now lets cut off everything but the first column to get the hash:

```
git ls-remote REPOLINK | grep TAG | sed -n 2p | cut -f1
```
