Git標簽操作

標簽操作允許為存儲庫中的特定版本提供有意義的名稱。 假設項目中有兩個程序員：maxsu和minsu，他們決定標記項目代碼，以便以后可以更容易訪問這些代碼。

創建標簽

使用git tag命令來標記當前HEAD指針。在創建標簽時需要提供-a選項的標簽名稱，并提供帶-m選項的標簽消息。

$ pwd
/D/worksp/sample

Administrator@MY-PC /D/worksp/sample (master)
$ git tag -a 'Release_1_0' -m 'Tagged basic string operation code' HEAD

如果要標記特定提交，則使用相應的COMMIT ID而不是HEAD指針。使用以下命令將標簽推送到遠程存儲庫。

$ git push origin tag Release_1_0

Total 1 (delta 0), reused 0 (delta 0)
To http://git.oschina.net/bjpowernode/sample.git
 * [new tag]         Release_1_0 -> Release_1_0

查看標簽

假設開發人員(maxsu)創建了標簽。 現在，另外一個開發人員(minsu)就可以使用帶有-l選項的git tag命令查看所有可用的標簽。

bjpowernode@ubuntu:~/git/sample$ pwd
/home/bjpowernode/git/sample

bjpowernode@ubuntu:~/git/sample$ git pull

 * [new tag]         Release_1_0 -> Release_1_0
Already up-to-date.

bjpowernode@ubuntu:~/git/sample$ git tag -l
Release_1_0
bjpowernode@ubuntu:~/git/sample$

可使用git show命令后跟其標簽名來查看有關標簽的更多詳細信息。

$ git show Release_1_0
tag Release_1_0

刪除標簽

使用以下命令從本地以及遠程存儲庫中刪除標簽，注意使用 git tag -d 中帶有-d選項：

$ git tag
Release_1_0

Administrator@MY-PC /D/worksp/sample (master)

$ git tag -d Release_1_0
Deleted tag 'Release_1_0' (was 600fa78)

Administrator@MY-PC /D/worksp/sample (master)

$ git push origin :Release_1_0
