An article explaining the usage of git push in detail

Usage of git push

In software development, GIT is a commonly used version control system, often used for collaborative development and version control. Among them, git push is a command in GIT, which is a command to submit local code to a remote warehouse. This article mainly introduces the usage of git push and related precautions.

1. Basic usage

The basic syntax of git push is as follows:

git push [远程库名] [本地分支名]:[远程分支名]

We can interpret this command as: push the local branch to the specified remote library on the branch.

For example, if we push the local branch master to the master branch of the remote library origin, we can use the following command:

git push origin master:master

In this command, origin is the remote library The name, master refers to the name of the local branch, and the master after the colon refers to the name of the remote branch. In this case, the name of the local branch and the remote branch are the same, so it can be abbreviated to:

git push origin master

2. Force overwriting of the remote branch

Sometimes, the local branch There is a conflict between the content of the remote branch and the content of the remote branch. We need to force the remote branch to be overwritten. You can use the following command:

git push -f [远程库名] [本地分支名]:[远程分支名]

For example, if we need to force the remote branch origin/master to be overwritten, you can use the following command:

git push -f origin master:master

It should be noted that force push may overwrite other people's work. So use it with caution.

3. Configuring the default push branch

Every time we use git push, we need to manually specify the local branch and remote branch. If we don't want to specify the branch name every time, we can configure git to use the corresponding branch name by default. You can use the following command:

git push --set-upstream [远程库名] [本地分支名]:[远程分支名]

For example, if we want to push the local branch dev to the dev branch of the remote library origin and make it the default push branch, you can use the following command:

git push --set-upstream origin dev:dev

In this way, every time you use git push in the future, you only need to execute the following command:

git push

to complete the push operation.

4. Other notes

It should be noted that before executing git push, you must first perform git add and git commit operations, otherwise git push will fail. In addition, pay attention to comparing the code and versions before submitting to avoid unnecessary code conflicts and errors.

In addition, if you want to view the current git configuration information, you can use the following command:

git config -l

Through the understanding of the above common commands and precautions, I hope it can help readers better master git push. Usage to avoid unnecessary errors and conflicts.
