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.

我也想知道正确的方法，但你总是可以窥探到:

$ cat .git/packed-refs 

or:

$ cat .git/refs/tags/*

这个怎么样:

git log -1 $TAGNAME

OR

git log -1 origin/$TAGNAME

如果您想查看标记SOMETAG(标记器，日期等)的详细信息，它所指向的提交的哈希值和一些关于提交的信息，但没有完整的差异，请尝试

git show --name-status SOMETAG

示例输出:

tag SOMETAG
Tagger: ....
Date:   Thu Jan 26 17:40:53 2017 +0100

 .... tag message .......

commit 9f00ce27c924c7e972e96be7392918b826a3fad9

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
