廖雪峰老师Git教程知识整理(4)-标签管理

接下来我们说一下

Git

中的标签。标签就是每个版本的快照。标签是指向提交的，前面说过没做一次

commit

就会生成一个

id

。但是取得每次的版本那么长的

id

则显得很不方便，所以我们引入了标签。

1.创建标签

在

Git

中打标签我们首先要切换到分支上，我们在

dev

分支上打标签

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (master)
$ git checkout dev
Switched to branch 'dev'

创建标签，默认在当前提交上创建标签，

git tag

命令可以查看所有标签，按照字母排序

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git tag v1.0

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git tag
v1.0

给历史版本打标签

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git log
commit 717dacfa38c94479201f686fdbe1444fad7f3f18 (HEAD -> dev, tag: v1.0, origin/dev)

Author: yz <357823669@qq.com>
Date:   Wed Jan 24 14:26:04 2018 +0800

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git tag v0.9 a78cf2877ab4db6672258bc1bb815

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git tag
v0.9
v1.0

使用

git tag -a -m

-a

标签名

-m

描述

git show <标签名>

查看标签信息

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git tag -a v1.1 -m "tagsrc" 3a078026b6a5c6b6f97700

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git tag
v0.9
v1.0
v1.1

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git show v1.1
tag v1.1
Tagger: yz <357823669@qq.com>

2.操作标签

删除标签

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git tag
v0.9
v1.0
v1.1

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git tag -d v0.9
Deleted tag 'v0.9' (was a78cf28)

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git tag
v1.0
v1.1

将标签推送到

GitHub

以及全部推送

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git push origin v1.0
Total 0 (delta 0), reused 0 (delta 0)
To github.com:RisingSunYZ/studygit.git
* [new tag]         v1.0 -> v1.0

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git push origin --tags
Counting objects: 1, done.
Writing objects: 100% (1/1), 148 bytes | 74.00 KiB/s, done.
Total 1 (delta 0), reused 0 (delta 0)
To github.com:RisingSunYZ/studygit.git
* [new tag]         v1.1 -> v1.1

如果已经推送到远程删除分两步

1 先删除本地标签

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git tag -d v1.0
Deleted tag 'v1.0' (was 717dacf)

2 再删除远程库中标签

admin@DESKTOP-6HL5242 MINGW64 /c/studygit (dev)
$ git push origin :refs/tags/v1.0
To github.com:RisingSunYZ/studygit.git
- [deleted]         v1.0
