如何从远程 git 存储库获取最新提交的 SHA？

Question

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?

Answer 1

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 

Answer 2

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.

Answer 3

A colleague of mine answered this for me:

git ls-remote ssh://git.dev.pages/opt/git/repos/dev.git <branch>

Answer 4

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>

Answer 5

As mentioned in comments above this should be the best solution:

$ git ls-remote <URL> | head -1 | cut -f 1

Answer 6

This should do the trick git ls-remote REMOTE | awk "/BRANCH/ {print \$1}" 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.

Answer 7

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

Answer 8

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

Answer 9

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.

Answer 10

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;}'

Answer 11

with gituhb desktop, it's easy!

1. First go to your repository on github desktop initial screen after selecting a repository

2. Then go to History Hisotry of pushes in that repo

3. Then, right click on the push you want SHA key of, and then copy the SHA key, from the pop up menu.

Menu after right click, to get SHA key
