允许有意义的名称到一个特定的版本库中的标签操作。Sampson 决定标记他们的项目代码,以便他们以后可以更容易访问。
## 创建标签
让我们标记当前HEAD使用git tag命令。他提供的标记名称前加上-a选项,使用-m选项,并提供标签信息。
sampson@CentOS project]$ pwd
/home/sampson/top_repo/project
[sampson@CentOS project]$ git tag -a 'Release_1_0' -m 'Tagged basic string operation code' HEAD
如果想标记特定提交然后使用适当的COMMIT ID,而不是HEAD 指针。 Sampson使用下面的命令推到远程存储库中的标签。
[sampson@CentOS project]$ git push origin tag Release_1_0
上面的命令会产生以下结果。
Counting objects: 1, done.
Writing objects: 100% (1/1), 183 bytes, done.
Total 1 (delta 0), reused 0 (delta 0)
To gituser@git.server.com:project.git
* [new tag]
Release_1_0 −> Release_1_0
## 查看标签
Sampson 创建标签。现在,Byron 可以查看所有可用标签通过使用Git tag命令使用-l选项。
[byron@CentOS src]$ pwd
/home/byron/byron_repo/project/src
[byron@CentOS src]$ git pull
remote: Counting objects: 1, done.
remote: Total 1 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (1/1), done.
From git.server.com:project
* [new tag]
Release_1_0 −> Release_1_0
Current branch master is up to date.
[byron@CentOS src]$ git tag -l
Release_1_0
Byron 使用Git的show命令后跟标记名称的有关标签查看更多细节。
[byron@CentOS src]$ git show Release_1_0
上面的命令会产生以下结果。
tag Release_1_0

[sampson@CentOS project]$ git tag -d Release_1_0
Deleted tag 'Release_1_0' (was 0f81ff4)
