命令从分支中获取最新的git提交散列 [英] Command to get latest git commit hash from a branch

问题描述

如何使用命令行检查特定git分支的最新提交散列？ 使用<$ c 使用 git ls-remote git：//github.com/< user> /< project> .git 。例如，我的trac-backlog项目给出了：

$ p $ g $ ls-remote git： TRAC-backlog.git

9db35263a15dcdfbc19ed0a1f7a9e29a40507070 refs / tags / 0.3.0 ^ {}

只需grep就可以找到你需要的东西并剪下来：

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

或者，您可以在命令中指定想要的参数并避免grep：

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

注意：它没有必须是 git：// url，它可以是 https：// 或 [e-mail]：。

How can I check with the command line the latest commit hash of a particular git branch?

解决方案

Use git ls-remote git://github.com/<user>/<project>.git. For example, my trac-backlog project gives:

:: git ls-remote git://github.com/jszakmeister/trac-backlog.git
5d6a3c973c254378738bdbc85d72f14aefa316a0    HEAD

Just grep for the one you need and cut it out:

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

Or, you can specify which refs you want on the command line and avoid the grep with:

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

Note: it doesn't have to be the git:// url, it could be https:// or [e-mail]: too.
