| 00:01 | Welcome to the spoken tutorial on Tagging in Git. |
| 00:06 | In this tutorial, we will learn about:
Tagging and Types of tagging. |
| 00:12 | For this tutorial, I am using:
Ubuntu Linux 14.04 Git 2.3.2 and gedit Text Editor You can use any editor of your choice. |
| 00:28 | To follow this tutorial-
You must have knowledge of running Linux commands on Terminal. If not, for relevant Linux tutorials, please visit our website. |
| 00:41 | Let us learn about tagging. |
| 00:44 | Tagging is used to mark a commit stage as important. |
| 00:49 | We can tag a commit, like a bookmark, for future references. |
| 00:54 | Typically, this is used to mark release point of a project such as v1.0. |
| 01:02 | There are two types of tags:
Lightweight tag and Annotated tag |
| 01:09 | First, I will demonstrate how to create a lightweight tag. |
| 01:15 | Let us go to our Git repository mywebpage which we created earlier. |
| 01:21 | Switch back to the terminal and type: cd space mywebpage and press Enter. |
| 01:30 | I will continue to use html files for demonstration. |
| 01:34 | You may use any file type of your choice. |
| 01:39 | Let’s check the Git log by typing git space log space hyphen hyphen oneline and press Enter. |
| 01:48 | Currently, we have three commits in our repository ,namely- "Added colors, Added history.html" and the "Initial commit". |
| 01:59 | Now, I will create a lightweight tag in the latest commit “Added colors”. |
| 02:05 | When we create a tag, by default, it will be created in the latest commit. |
| 02:12 | Type: git space tag space v1.1 and press Enter. |
| 02:20 | Here, I will give v1.1 as the tag name. You can give any name of your choice. |
| 02:29 | You can see the tag by typing git space tag and press Enter. |
| 02:35 | Now, we have only one tag in our repository. |
| 02:39 | Next, we will learn how to create an annotated tag. |
| 02:44 | First, I will make some modifications in the file mypage.html for demonstration purpose. |
| 02:52 | Type: gedit space mypage.html space ampersand and press Enter. Let us add some lines in the file. |
| 03:04 | Then save and close the file. |
| 03:07 | Let’s commit our work at this point. |
| 03:11 | Type: git space commit space hyphen a m space within double quotes “Added content in mypage.html” and press Enter. |
| 03:25 | Let us assume that this particular stage is very important to the project. |
| 03:31 | So, we have to create a tag at this commit point. |
| 03:35 | Here, we will create an annotated tag. |
| 03:39 | Type: git space tag space hyphen a space v1.2 space hyphen m space within double quotes “My Version 1.2” and press Enter. |
| 03:55 | Using -m flag, you can give any tag message of your choice. |
| 04:01 | Here, the tag message is optional. |
| 04:05 | To see the tag list, type: git space tag and press Enter. Now we have two tags. |
| 04:14 | Here, v1.1 is the lightweight tag and v1.2 is the annotated tag. |
| 04:21 | How do we differentiate between the tags? |
| 04:24 | We can see the difference between the two tags by using git show command. |
| 04:31 | Type: git space show space v1.1 and press Enter. |
| 04:38 | Here, we can see the complete details of the lightweight tag v1.1. |
| 04:44 | It simply shows the commit details and the file changes. |
| 04:50 | Next, we will see the details of the annotated tag v1.2. Type: git space show space v1.2 and press Enter. |
| 05:03 | Here we can see the:
tag name tagger details date the commit was tagged tag message commit details and file changes. |
| 05:17 | Annotated tag is always recommended when you work collaboratively. |
| 05:23 | Let us now learn how to mark a tag in our old commits. |
| 05:29 | First, we will check the Git log by typing git space log space hyphen hyphen oneline and press Enter. |
| 05:39 | Now, for instance, I want to create a tag in my second commit “Added history.html”. |
| 05:47 | Type: git space tag space hyphen a space v1.0 space. Then, copy and paste the commit hash of the “Added history.html” space type: hyphen m space within double quotes “My Version 1.0” and press Enter. |
| 06:09 | We will be able to see the tag which we created now, by typing git space tag and press Enter. |
| 06:19 | You can see the tag v1.0 is created here. |
| 06:24 | Next, we will learn how to see the tags along with the Git log. |
| 06:29 | Type: git space log space hyphen hyphen oneline space hyphen hyphen decorate and press Enter. |
| 06:40 | You can see the Git log along with the tag names. |
| 06:44 | Now, we will learn to delete an unwanted tag. |
| 06:49 | Say, I want to delete the tag v1.1. |
| 06:53 | Type: git space tag space hyphen d space v1.1 and press Enter. |
| 07:02 | It shows the message “Deleted tag 'v1.1'” and its commit hash. |
| 07:08 | We will check whether the tag is deleted or not. |
| 07:14 | Type: git space tag and press Enter. |
| 07:19 | Now, we can't see the tag v1.1 as it has been deleted successfully. |
| 07:25 | With this, we come to the end of this tutorial. |
| 07:29 | Let us summarize. In this tutorial, we have learnt about:
Tagging and Types of tagging. |
| 07:38 | As an assignment-
Create a lightweight tag and an annotated tag and Understand the difference between both the tags. |
