git bash : how to check if there’s a new commit available

我正在编写一个脚本，在该脚本中，我想将最新的本地提交与最新的上游提交进行比较，以告诉用户有待提交的提交.

I am writing a script where I would like to compare the latest local commit to the latest upstream commit in order to tell the user there are commits to be pulled.

最新的本地提交SHA显示为git log | head -n 1 | awk '{print $2}'.

The latest local commit SHA is displayed with git log | head -n 1 | awk '{print $2}'.

是否有等效功能可打印最新的上游提交的SHA1?

Is there an equivalent for printing the SHA1 of the latest upstream commit?

推荐答案

本地标题:

$ git rev-parse HEAD

远程头:

$ git ls-remote <url> <refs>

显示远程存储库中可用的引用以及关联的提交ID.

Displays references available in a remote repository along with the associated commit IDs.

示例:

$ cd ~/github/scrapy/scrapy
$ git rev-parse HEAD
9f003a73daec59a73c23a2214b1b8d15a4391a2f
$ git ls-remote git://github.com/scrapy/scrapy.git HEAD
9f003a73daec59a73c23a2214b1b8d15a4391a2f

您可以使用diff比较两者的输出:

You can use diff to compare the output of the two:

$ diff <(git ls-remote git://github.com/scrapy/scrapy.git HEAD) \
       <(git rev-parse HEAD)
