标签管理
tag git中的标签 主要作用就是给某条修改记录取一个让人容易记住的有意义的名字，它跟某个commit绑在一起。
创建标签
给某次修改打一个标签该如何操作呢？下面的例子演示了如何给当前版本，打标签
$ git checkout master
Switched to branch 'master'
Your branch is up to date with 'rigion/master'.
$git tag v1.0
$ git tag
v1.0
bogon:git zhengbing$ git log --pretty=oneline

那么如果要给之前的版本打标签呢？这应该是很平常的需求吧？git tag v0.9 <记录号>a2fb2cda
$ git tag v0.9 a2fb2cda
$ git log --pretty=oneline

使用git tag 后面不跟参数的时候，可以查看当前版本库的标签
$ git tag
v0.9
v1.0
也可以使用 git show <tagname> 查看所打的标签的详细信息
$ git show v0.9
commit a2fb2cda5f71231c9c0dd3eea6c9d6b673121529 (tag: v0.9)
Author: zhengbing <mydreambing@126.com>
Date: Sat Oct 19 17:42:46 2019 +0800
delete readme2.txt
diff --git a/readme2.txt b/readme2.txt
deleted file mode 100644
index e69de29..0000000
和 git commit 一样 我们也可以给标签添加注释 同样使用git tag 命令 但是要加上参数了 -a 指定标签名 -m 添加注释
使用git show v0.8 可以看到我们给标签写的注释
$ git tag -a v0.8 -m 'finished september dev' f8ba521f5
$ git tag
v0.8
v0.9
v1.0
$ git show v0.8
tag v0.8

add file dev.txt
diff --git a/dev.txt b/dev.txt
new file mode 100644
index 0000000..e69de29
删除标签
ok，如果打错了标签呢？我们可能要删除标签。需要用到 git tag -d <tagname>
$ git tag -d v0.9
Deleted tag 'v0.9' (was a2fb2cd)
如果打的标签没有问题的话，那么我么就可以把本地的标签push到远程仓库进行管理
$ git push origin v1.0
Total 0 (delta 0), reused 0 (delta 0)
To github.com:zhengbinger/learngit.git
* [new tag] v1.0 -> v1.0
删除远程标签
那么，如果远程的标签打错了呢？怎么删除呢？
先删除本地标签
$ git tag -d v1.0
再删除远程标签，删除远程标签会比较复杂一点 git push origin :refs/tags/v1.0
$ git push origin :refs/tags/v1.0
To github.com:zhengbinger/learngit.git
- [deleted] v1.0
