Simple use of Git

1. Git repository Initialization

• This repository stores the files backed up by git for our project.

• Right-click the project directory and choose git bash.

• Command:git init

2. Configure user information:

• It is to set who the current user is. After each backup, the information of the backup user is stored.

• Command:

  • Configuration Username:git config --global user.name "wanglong"

  • Configuration Email:git config --global user.email "[email protected]"

3. Store the code in the. Git Repository:

• 1. Put the code in the GIT staging area:

  • git add ./01.txt: Place the specified file in the temporary storage area.

  • git add ./: Put all modified files in the temporary storage area.

• 2. Store the file at the warehouse entry to the version Library:

  • Git commit-M "file description".

• 3. All modified files can be put into the version library at one time + command:Git commit -- all-M "some instructions"

4. view the current status

• You can check whether the current code has been put into the warehouse:

• Command:git status.

5. Ignore files in git

• . Gitignore: Set the ignored files and directories in this file.

• Ignored files are not submitted to the warehouse.

• Statement:

  • /..dea: The. DEA file is ignored.

• git log: View historical submitted logs

• git log --oneline: You can view the logs of the simplified version.

7. Roll Back to the specified version

• git reset --hard Head~0: Indicates to roll back to the status of the last code submission (may be 0, 1, 2 ...).

• Git reset -- hard [version number]: Accurately rolls back to a submitted status.

• git reflog: You can see the record of each version switch: You can see all submitted version numbers.

8. Branch

• git branch: View the current branches

• git merge dev: Merge Branch

  • Merge the current branch with the specified branch.

• git branch -d dev: Delete Branch

• When there is a conflict in the merge (manual merge is required), delete unnecessary components and resubmit the modified Code.

Submit code to GitHub

• Git push address (the content of the current branch will be uploaded to the remote master Branch) Master

Obtain data from GitHub warehouse

• git pull https://github.com/nameWangLong/test01.git master+ Before downloading, You need to initialize a repositories.

• Git clone [address]: A New file is created to obtain the file in the remote warehouse. Multiple operations will overwrite the file.

Upload code using SSH:

• Public Key and Private Key

• Command for generating public and private keys:Ssh-keygen-t rsa-c "email"

• Add the generated public key or private key to SSH in GitHub Project Settings

• git push [email protected]:nameWangLong/test01.git master

Push and pull operation sequence:

• Pull first resolves conflicts and then pushes them to the server.

Push and pull for simplified operations

• First, define a Remote Variable pointing to the address:git remote add origin [email protected]:nameWangLong/test01.git master

• Then add the-u parameter to the push type.git push origin -u master

• After uploading and downloading, you only need to entergit push git pull
