How to use Git for push operations

In the software development process, version management is an important task. As one of the most commonly used version management tools, Git can help team collaboration be more efficient. In Git, the push operation is to push the local code to the remote warehouse. This article will introduce how to use Git to perform the push operation.

1. Enable SSH authentication

If you have completed copying the remote warehouse, you need to enable SSH authentication first. Open the terminal (MacOS/Linux) or Git Bash (Windows) and enter the following command:

ssh-keygen -t rsa -C "your_email@example.com"

Among them, "your_email@example.com" needs to be replaced with the email address used to register GitHub/GitLab. Press Enter and the public/private key pair will be created:

Generating public/private rsa key pair.
Enter file in which to save the key (/Users/you/.ssh/id_rsa):

Follow the prompts to complete the settings step by step. After completion, use the following command to add SSH verification to the Agent:

eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_rsa

2. Add remote repository

Run the command under the local code repository:

git remote add origin git@xxxxxx.git

Among them, origin is the name of the remote repository, which can be changed freely according to preference. , git@xxxxxx.git is the remote warehouse address in SSH format and should be replaced with the actual address.

3. Check the local repository

Before synchronizing to the remote repository, make sure that the local code repository is in the correct branch. You can use the following command to view the current branch:

git branch

In the output of this command, the branch with * in front of it is the current branch.

4. Submit code

After completing the code modification, run the following command to temporarily store the changes to the local warehouse:

git add .

where. means all files in the current folder. To commit changes to only certain files, replace . with the file name.

Submit changes:

git commit -m "commit message"

Among them, commit message should be filled with meaningful comments to facilitate subsequent management. For example, "XX function has been modified" etc.

5. Push to the remote warehouse

Since SSH authentication is turned on, the local code is pushed to the remote warehouse through the following command:

git push origin branch_name

Among them, branch_name should fill in the name of the branch that needs to be pushed, usually master.

After completing the above steps, the code will be submitted to the remote warehouse.

6. Encounter a push failure

If you encounter a failure during the push process, you can first pull the latest version of the remote warehouse through the following command, and then perform the push operation:

git pull origin branch_name

If there is a conflict in the modification, you will be prompted to manually resolve the conflict. After manually solving it, just submit it again.

The above is the detailed process of Git push operation. I hope readers can master it and apply it skillfully.
