一、创建标签

标签tag，是对某次 commit 的⼀个标识，相当于起了⼀个别名。

相较于难以记住的 commit id ， tag 很好的解决这个问题，因为 tag ⼀定要给⼀个让⼈容易记住，且有意义的名字。当我们需要回退到某个重要版本时，直接使⽤标签就能很快定位到。

# 切换到需要打标签的分支上，用 git tag [name] 给分支打标签
# 用 git tag 查看标签

(base) [root@localhost git-learning]# git branch
* master
(base) [root@localhost git-learning]# git tag v1.0
(base) [root@localhost git-learning]# git tag
v1.0
(base) [root@localhost git-learning]#

# 默认标签是打在最新提交的 commit 上，我们也可以指定 commit id 打标签

(base) [root@localhost git-learning]# git log --pretty=oneline --abbrev-commit
8d78346 add files: file.ini file.so
1ccab43 Git在线修改 file1.
ec3bb79 add first file
dd56a90 Initial commit
(base) [root@localhost git-learning]# git tag v0.0 1ccab43
(base) [root@localhost git-learning]# git tag
v0.0
v1.0
(base) [root@localhost git-learning]#

二、查看标签

git tag 查看标签不是按时间顺序列出，而是按字母排列的。

# git show [tagname] 查看标签具体信息

(base) [root@localhost git-learning]# git show v0.0

三、推送标签

# 将标签推送到远程仓库

(base) [root@localhost git-learning]# git tag
v0.0
v1.0
(base) [root@localhost git-learning]# git push origin v1.0
Total 0 (delta 0), reused 0 (delta 0)
remote: Powered by GITEE.COM [1.1.5]
remote: Set trace flag 724b2093
To git@gitee.com:hdu-a-chao/git-learning.git
 * [new tag]         v1.0 -> v1.0
(base) [root@localhost git-learning]# 

四、删除标签

# 如果标签打错了，可以用 git tag -d [tagname] 删除标签

(base) [root@localhost git-learning]# git tag -d v0.0
已删除 tag 'v0.0'（曾为 1ccab43）
(base) [root@localhost git-learning]# git tag
v1.0
(base) [root@localhost git-learning]#

# 如果已经将标签推送到远程仓库，想要删除标签怎么办？
# 先在本地仓库删除，再将本地仓库推送到远程仓库

(base) [root@localhost git-learning]# git tag
v1.0
(base) [root@localhost git-learning]# git tag -d v1.0
已删除 tag 'v1.0'（曾为 8d78346）
(base) [root@localhost git-learning]# git push origin :refs/tags/v1.0
remote: Powered by GITEE.COM [1.1.5]
remote: Set trace flag 274a87aa
To git@gitee.com:hdu-a-chao/git-learning.git
