What is the difference between commit and push under git?

Difference: 1. The "git commit" command submits locally modified files to the local library, while the "git push" command sends the latest information in the local library to the remote library; 2. " The "git commit" command operates the local library, while the "git push" command operates the remote library.

The operating environment of this tutorial: Windows 7 system, Git version 2.30.0, Dell G3 computer.

The difference between "git commit" and "git push"

git commitis "recording the changes to the repository" Change" is to submit locally modified files to the local library; andgit pushis to "update remote references and related objects", which is to send the latest information in the local library to the remote library.

Therefore,git commitis used to connect to the local repository and operates the local library; andgit pushis used to interact with the remote repository and operates the remote library.

Here's a good picture from Oliver Steele explaining the Git model and commands:

Git commit

git commitMainly commits the changes in the temporary storage area to the local repository. Every time we use the git commit command, we will generate a 40-digit hash value in the local repository. This hash value is also called commit-id.

Commit-id is very useful when rolling back the version. , it is equivalent to a snapshot, which can be returned to here at any time in the future through the combined command with git reset.

1、git commit -m 'message'

## The #-m parameter means that you can directly enter the following "message". If you do not add the -m parameter, you cannot directly enter the message. Instead, an editor, usually vim, will be called to let you enter the message.

message is the statement we use to briefly describe this submission.

2,

git commit -am 'message' -amis equivalent to -a -m

-a parameter can modify or delete the execution in all tracked files The operated files are submitted to the local warehouse, even if they have not been added to the staging area through git add.

Note: Newly added files (that is, files that are not managed by the git system) cannot be submitted to the local warehouse. of.

Git push

Use the

git commitcommand to commit the modifications from the staging area After arriving at the local repository, only the last step is left to push the branch of the local repository to the corresponding branch on the remote server. If you are not sure about the composition of the repository, you can check out my other article, the basic structure of the git warehouse. The general form of

git pushisgit push , for examplegit push origin master: refs/for/master , which is to push the local master branch to the corresponding master branch on the remote host origin, where origin is the name of the remote host. The first master is the local branch name, and the second master is the remote branch name.

1,

git push origin master

If the remote branch is omitted, as above, it means pushing the local branch to the remote branch with which there is a tracking relationship (usually both same name), if the remote branch does not exist, it will be created

2,

git push origin: refs/for/master

If the local branch name is omitted, then Indicates deleting the specified remote branch, because this is equivalent to pushing an empty local branch to the remote branch, which is equivalent to git push origin –delete master

3,

git push origin

If there is a tracking relationship between the current branch and the remote branch, both the local branch and the remote branch can be omitted, and the current branch will be pushed to the corresponding branch of the origin host

4,

git push

If the current branch has only one remote branch, the host name can be omitted, such as git push. You can use git branch -r to view the remote branch name
