Git Add. Add all files to the version Library
git clean -fClear Untracked files
git commit -m "wrote a test file" Submit the modified file to the repository. The-M parameter is used to set the comments for this submission. git commit -a -m "wrote a test file" If multiple files need to be submitted, you must use the-a parameter.

Git status: Check the current status of the Repository. It shows the files that have been modified and those files need to be submitted.

Git log view other parameters of version submission records
Git log -- stat view brief statistics on the number of rows to be added and changed for the Submission record
Git log -- pretty = oneline only displays the commit ID (version number) and comments of the submission record git log --pretty=oneline --abbrev-commit

Git reset -- hard head ^ roll back the current version to the previous version
git reset --hard HEAD～100    
Git reset -- hard commit_id: roll back to the specified version number


Git reflog view Command Execution records Git diff head -- view the differences between the latest version in the workspace and version library for file names

Git checkout -- readme.txt undo all the modifications to the file in the workspace and roll back to the latest version in the version library or temporary storage zone.
Git reset head readme.txt: roll back the changes in the temporary storage area to the Work Area


Git RM readme.txt delete files from the version Library
git show A hash file submitted View the modification record of a file

git remote add origin [email protected]:username/learngit.gitAssociate the local git library with the remote database. The origin is the name of the remote database (which can be defined as needed)

Git push-u origin master pushes all the content of the master branch in the local database to the remote database. The-u parameter is used to associate the local database with the remote database. This parameter is not required for normal submission.


Ssh-keygen-t rsa-c "[email protected]" creates an SSH key. Each client creates a key. GitHub can accurately identify the submitter when submitting the key.
