从分支获取最新git commit hash的命令

Question

如何在命令行中检查特定git分支的最新提交哈希？

Answer 1

git log -n 1 [branch_name]

branch_name(可能是远程或本地分支)是可选的.如果没有branch_name,它将显示当前分支的最新提交.

例如:

git log -n 1
git log -n 1 origin/master
git log -n 1 some_local_branch

git log -n 1 --pretty=format:"%H"  #To get only hash value of commit

Answer 2

使用git ls-remote git://github.com/<user>/<project>.git.例如,我的trac-backlog项目给出:

:: git ls-remote git://github.com/jszakmeister/trac-backlog.git

只需grep你需要的那个并切掉它:

:: git ls-remote git://github.com/jszakmeister/trac-backlog.git | \
   grep refs/heads/master | cut -f 1

或者,您可以在命令行中指定所需的引用,并避免使用grep:

:: git ls-remote git://github.com/jszakmeister/trac-backlog.git refs/heads/master | \
   cut -f 1
5d6a3c973c254378738bdbc85d72f14aefa316a0

注意:它不必是git://URL,它可能是https://或git@github.com:过.
