How to get SHA of the latest commit from remote git repository?
GitGit Problem Overview
Does anyone know how to get the latest SHA of a given branch from outside a git repository?
If you are inside a git repository, you can do:
git log origin/branch_X | head -1
However, I am not inside a git repository, and I would like to avoid having to clone a repository just to get the latest SHA of a tag/branch. Is there a clever way of doing this?
Git Solutions
Solution 1 - Git
Use rev-parse
git rev-parse origin/master # to get the latest commit on the remote
git rev-parse HEAD # to get the latest commit on the local
Solution 2 - Git
If you want to check SHA-1 of given branch in remote repository, then your answer is correct:
$ git ls-remote <URL>
However if you are on the same filesystem simpler solution (not requiring to extract SHA-1 from output) would be simply:
$ git --git-dir=/path/to/repo/.git rev-parse origin/branch_X
See git(1) manpage for description of '--git-dir' option.
Solution 3 - Git
A colleague of mine answered this for me:
git ls-remote ssh://git.dev.pages/opt/git/repos/dev.git <branch>
Solution 4 - Git
Using a git URL:
$ git ls-remote <URL> | head -1 | sed "s/HEAD//"
Using a directory on an accessible system:
$ git --git-dir=/path/to/repo/.git rev-parse origin/<targeted-banch>
Solution 5 - Git
As mentioned in comments above this should be the best solution:
$ git ls-remote <URL> | head -1 | cut -f 1
Solution 6 - Git
This should do the trick git ls-remote REMOTE | awk "/BRANCH/ {print \$1}"
Replace REMOTE with the name of the remote repository and BRANCH with the name of the branch.
Solution 7 - Git
If you just want the SHA-1 from the currently checked out branch of your local repo, you can just specify HEAD instead of origin/branch_X:
git --git-dir=/path/to/repo/.git rev-parse --verify HEAD
Solution 8 - Git
Heres a copy-paste solution which works inside the repository.
origin_head=$(git ls-remote --heads $(git config --get remote.origin.url) | grep "refs/heads/master" | cut -f 1)
if [ $origin_head != "$(git rev-parse HEAD)" ]; then
echo >&2 "HEAD and origin/master differ."
exit 1
fi
Solution 9 - Git
References to branch heads are stored in the .git/refs/ tree. So you should be able to find the hash of the latest commit at:
cat .git/refs/remotes/origin/branch_X
Your path may differ slightly.
Solution 10 - Git
I recommend fetching info related only to a given branch, and then parse to get the latest sha:
git ls-remote <url> --tags <branch_name> | awk '{print $1;}'
Solution 11 - Git
with gituhb desktop, it's easy!
-
First go to your repository on github desktop initial screen after selecting a repository
-
Then go to History Hisotry of pushes in that repo
-
Then, right click on the push you want SHA key of, and then copy the SHA key, from the pop up menu.
