Linux git(16)----创建标签

用到的新命令
1.git tag 标签标记：在当前分支上打标签(可带参数的-a、-m)(默认标签是打在最新提交的commit上的)
2.git tag:查看当前分支的标签(标签不是按时间顺序列出，而是按字母排序的)
3.git show 标签标记:查看指定标签标签信息


1.在当前分支上打标签
[root@VM_0_11_centos learn_git]# git checkout master 
Already on 'master'
[root@VM_0_11_centos learn_git]# git tag v1.0
[root@VM_0_11_centos learn_git]# git tag 
v1.0


2.在历史commit的 merged bug fix 101打标签，id为2cf8f0b
[root@VM_0_11_centos learn_git]# git log --pretty=oneline --abbrev-commit
