Complete steps to pull git code

With the popularity of open source software, more and more developers are beginning to use Git as a version management tool. On the basis of Git, platforms such as GitHub, GitLab, and Bitbucket have also been launched one after another, making collaborative development more convenient. But for novices, using Git is still relatively difficult. One of the most basic operations is to clone the code. This article will detail the complete steps to pull Git code.

1. Installing Git

Before you start, you need to ensure that you have installed Git and set up the global user name and email address of Git. If you have not installed Git, please go to the Git official website https://git-scm.com/downloads to download and install it.

After the installation is completed, enter the following command in the terminal window to verify whether the installation is successful:

$ git --version

If Git has been installed correctly, the Git version number will be displayed.

2. Get the code repository URL

Before pulling the code, you need to get the code repository URL. Generally speaking, you can find the URL of the warehouse on the project page of the code hosting platform. Taking GitHub as an example, you can click the "Clone or download" button on the project page and copy the URL of the warehouse.

3. Run the git clone command in the terminal

After obtaining the URL of the code warehouse, open the terminal window and enter the following command:

$ git clone <URL>

where <URL> represents the URL of the code repository you obtained.

For example, if you want to pull the code of the warehouse from GitHub, you can use this URL:

$ git clone https://github.com/username/repository.git

Tip: Sometimes the copied URL starts with the ssh protocol. It needs to be converted to https protocol. The specific operation can be found on the project page.

4. Get the latest code

Once you use the git clone command, Git will download all the code files to your local computer . But if other developers modify some files and submit the code after you pull the code, then your local code will be out of date. To ensure that you have the latest code, you need to use the following command to get the latest code:

$ git pull

This command will pull the latest commits from the remote repository and merge them into your local repository.

5. Switch to the specified branch

In Git, each branch is equivalent to an independent code branch. The code between different branches can be developed independently and eventually merged into the trunk. Therefore, after pulling the code, you need to switch to the corresponding development branch for development. You can use the following command to view the local branch:

$ git branch

If you need to switch to a branch, you can use the following command:

$ git checkout <branch-name>

where<branch-name> is the name of the branch you need to switch to.

6. Changes and commits in the working directory

After you pull the code from the remote warehouse, you can make changes and commits in the working directory. If you have modified some files and want to commit them to the remote repository, you need to execute the following command:

$ git add <file-name>
$ git commit -m "commit message"
$ git push

• git add <file-name>: The The command will add the files you modified to the Git staging area, ready for submission.
• git commit -m "commit message": This command will submit all your modifications in the staging area to the local Git repository at once. This submission also requires a submission message, which can be specified in the -m parameter.
• git push: This command pushes the submissions in your local warehouse to the remote warehouse.

7. End the work

Finally, when your work is completed, you can use the following command to close the local Git repository:

$ git remote prune origin
$ git gc

This can be deleted Useless remote branches and clean up abandoned objects in the local warehouse.

Okay, the above are the complete steps to pull the Git code. I hope this article can help you use Git better.
