$ git branch
* dev
master
$ git checkout master
Switched to branch ‘master‘
然后,敲命令git tag <name>
就可以打一个新标签:
$ git tag v1.0
可以用命令git tag
查看所有标签:
$ git tag
v1.0
默认标签是打在最新提交的commit上的。有时候,如果忘了打标签,比如,现在已经是周五了,但应该在周一打的标签没有打,怎么办?
方法是找到历史提交的commit id,然后打上就可以了:
$ git log --pretty=oneline --abbrev-commit
12a631b (HEAD -> master, tag: v1.0, origin/master) merged bug fix 101
4c805e2 fix bug 101
e1e9c68 merge with no-ff
f52c633 add merge
cf810e4 conflict fixed
5dc6824 & simple
14096d0 AND simple
b17d20e branch test
d46f35e remove test.txt
b84166e add test.txt
519219b git tracks changes
e43a48b understand how stage works
1094adb append GPL
e475afc add distributed
eaadf4e wrote a readme file
比方说要对add merge
这次提交打标签,它对应的commit id是f52c633
,敲入命令:
$ git tag v0.9 f52c633
再用命令git tag
查看标签:
$ git tag
v0.9
v1.0
注意,标签不是按时间顺序列出,而是按字母排序的。可以用git show <tagname>
查看标签信息:
$ git show v0.9
commit f52c63349bc3c1593499807e5c8e972b82c8f286 (tag: v0.9)
Author: Michael Liao <askxuefeng@gmail.com>
Date: Fri May 18 21:56:54 2018 +0800
add merge
diff --git a/readme.txt b/readme.txt
...
可以看到,v0.9
确实打在add merge
这次提交上。
还可以创建带有说明的标签,用-a
指定标签名,-m
指定说明文字:
$ git tag -a v0.1 -m "version 0.1 released" 1094adb
用命令git show <tagname>
可以看到说明文字:
$ git show v0.1 tag v0.1 Tagger: Michael Liao <askxuefeng@gmail.com> Date: Fri May 18 22:48:43 2018 +0800 version 0.1 released commit 1094adb7b9b3807259d8cb349e7df1d4d6477073 (tag: v0.1) Author: Michael Liao <askxuefeng@gmail.com> Date: Fri May 18 21:06:15 2018 +0800 append GPL diff --git a/readme.txt b/readme.txt
删除标签
$ git tag -d v0.1
Deleted tag ‘v0.1‘ (was f15b0dd)
因为创建的标签都只存储在本地,不会自动推送到远程。所以,打错的标签可以在本地安全删除。
如果要推送某个标签到远程,使用命令git push origin <tagname>
:
$ git push origin v1.0
Total 0 (delta 0), reused 0 (delta 0)
To github.com:michaelliao/learngit.git
* [new tag] v1.0 -> v1.0
或者,一次性推送全部尚未推送到远程的本地标签:
$ git push origin --tags
Total 0 (delta 0), reused 0 (delta 0)
To github.com:michaelliao/learngit.git
* [new tag] v0.9 -> v0.9
如果标签已经推送到远程,要删除远程标签就麻烦一点,先从本地删除:
$ git tag -d v0.9
Deleted tag ‘v0.9‘ (was f52c633)
然后,从远程删除。删除命令也是push,但是格式如下:
$ git push origin :refs/tags/v0.9
To github.com:michaelliao/learngit.git
- [deleted] v0.9
