How to get SHA of the latest commit from remote git repository?
提问by AdvilUser
Does anyone know how to get the latest SHA of a given branch from outsidea git repository?
有谁知道如何从git 存储库外部获取给定分支的最新 SHA ？
If you are inside a git repository, you can do:
如果您在 git 存储库中，则可以执行以下操作：
git log origin/branch_X | head -1
However, I am not inside a git repository, and I would like to avoid having to clonea repository just to get the latest SHA of a tag/branch. Is there a clever way of doing this?
但是，我不在 git 存储库中，我想避免clone为了获取标签/分支的最新 SHA 而不得不使用存储库。有没有聪明的方法来做到这一点？

If you want to check SHA-1 of given branch in remote repository, then your answeris correct:
如果您想检查远程存储库中给定分支的 SHA-1，那么您的答案是正确的：
$ 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:
但是，如果您在同一个文件系统上，更简单的解决方案（不需要从输出中提取 SHA-1）将很简单：
$ git --git-dir=/path/to/repo/.git rev-parse origin/branch_X
See git(1)manpage for description of '--git-dir' option.
有关“ ”选项的说明，请参见git(1)联机帮助页--git-dir。

A colleague of mine answered this for me:
我的一个同事为我回答了这个问题：
git ls-remote ssh://git.dev.pages/opt/git/repos/dev.git <branch>

Using a git URL:
使用 git URL：
$ git ls-remote <URL> | head -1 | sed "s/HEAD//"
Using a directory on an accessible system:
使用可访问系统上的目录：
$ git --git-dir=/path/to/repo/.git rev-parse origin/<targeted-banch>

This should do the trick git ls-remote REMOTE | awk "/BRANCH/ {print \$1}"
这应该可以解决问题 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.
将 REMOTE 替换为远程存储库的名称，将 BRANCH 替换为分支的名称。

As mentioned in comments above this should be the best solution:
正如上面的评论中提到的，这应该是最好的解决方案：
$ git ls-remote <URL> | head -1 | cut -f 1
$ git ls-remote <URL> | head -1 | cut -f 1
回答by kitingChris
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:
如果您只想要本地存储库当前签出的分支中的 SHA-1，则可以指定 HEAD 而不是 origin/branch_X：
git --git-dir=/path/to/repo/.git rev-parse --verify HEAD
git --git-dir=/path/to/repo/.git rev-parse --verify HEAD

Heres a copy-paste solution which works inside the repository.
这是一个在存储库内工作的复制粘贴解决方案。
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

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:
对分支头的引用存储在.git/refs/树中。因此，您应该能够在以下位置找到最新提交的哈希值：
cat .git/refs/remotes/origin/branch_X
Your path may differ slightly.
您的路径可能略有不同。

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;}'
我建议获取仅与给定分支相关的信息，然后解析以获取最新的 sha：git ls-remote <url> --tags <branch_name> | awk '{print $1;}'
