这将得到当前的SHA1哈希值

简化提交哈希

git show <tag> --format="%h" --> 42e646e

提交哈希

git show <tag> --format="%H" --> 42e646ea3483e156c58cf68925545fffaf4fb280

我也想知道“正确”的方法，但同时，你可以这样做:

git show mytag | head -1    

从git邮件列表中，可以通过自动对带注释的标签解引用来获得标签的提交哈希列表:

git for-each-ref --format='%(if)%(*objectname)%(then)%(*objectname)%(else)%(objectname)%(end) %(refname)' refs/tags

只需使用git show <tag>

但是，它也转储提交差异。要忽略这些差异，使用git log -1 <tag>。(感谢@DolphinDream和@demisx !)

format选项可用于显示标记散列和提交散列，并用于区分轻量级标记和带注释的标记。

git tag --format="%(color:bold cyan)== %(refname:short) ==%(if)%(object)%(then)%0aTag Hash: %(objectname)%0aTag Date: %(taggerdate:iso-local)%0a  Commit: %(object) %0a%0a%(contents)%(else)%0a(lightweight tag)%0a  Commit: %(objectname)%(end)%0a"

输出类似于:

== b2lightweight ==
(lightweight tag)
  Commit: 0450fae4352dbbbf088419757eda32711316a02e

== c3_annotated ==
Tag Hash: 19961d8678a09a319a9d6c398c79f27cc23d610c
Tag Date: 2021-08-06 15:18:48 -0600
  Commit: 85be6e80c109ce44d78f0ca0da8e1ec53817b24c

This is my tag message.

It has multiple lines.

Another line.

要定义为git别名，你可以使用git config——global -e编辑全局git配置，并添加以下内容:

[alias]
    tag-verbose = tag --format='%(color:bold cyan)== %(refname:short) ==%(if)%(object)%(then)%0aTag Hash: %(objectname)%0aTag Date: %(taggerdate:iso-local)%0a  Commit: %(object) %0a%0a%(contents)%(else)%0a(lightweight tag)%0a  Commit: %(objectname)%(end)%0a'

别名仍然允许过滤，例如。

C:\playground>git tag-verbose -l *b2*
== b2lightweight ==
(lightweight tag)
  Commit: 0450fae4352dbbbf088419757eda32711316a02e

总结

由于大约有4个几乎同样可接受但不同的答案，我将总结所有不同的方法来皮肤标签。

git rev-list -1 $TAG (answer). git rev-list outputs the commits that lead up to the $TAG similar to git log but only showing the SHA1 of the commit. The -1 limits the output to the commit it points at. git show-ref --tags (answer) will show all tags (local and fetched from remote) and their SHA1s. git show-ref $TAG (answer) will show the tag and its path along with the SHA1. git rev-parse $TAG (answer) will show the SHA1 of an unannotated tag. git rev-parse --verify $TAG^{commit} (answer) will show a SHA1 of both annotated and unannotated tags. On Windows use git rev-parse --verify %TAG%^^^^{commit} (four hats). cat .git/refs/tags/* or cat .git/packed-refs (answer) depending on whether or not the tag is local or fetched from remote.
