1. New warehouse

  • git initAfter initializing the repository, you can find an additional.git directory in the current directory
  • git remote add origin [email protected]:joel/test.gitThe local repository is associated with the remote repository. Origin is the default name and can be changed
  • git push -u origin masterPush all content from the local library to the remote library. Since the remote library is empty, the first time we push the master branch, we add it-uParameters (push and association), subsequent push can simplify instructions.

Two, commonly used modification instructions

  • git add xxx.txtAdd, but do not commit,git add.Add all files.
  • Git commit -mSubmit, only after add submission is valid.

Three, common view instructions

  • Git status Displays the current status of the repository

  • Git diff: git diff

  • Git diff version 1 Version 2 –stat Displays a list of files that are different between two versions, including the number of lines changed and the chart of additions and deletions. If the parameter is changed to –name-status, the modification description letter (A,M, etc.) is displayed before the parameter, and the number of lines is not displayed

  • Git branch Displays the current branch. The git branch command lists all branches, with the current branch preceded by an asterisk

  • Git log displays commit logs from the most recent to the most distant

  • Git remote Displays information about the remote repository

4. Undo modifications and version rollback

  • Git checkout -- file nameKill those without staging (i.e., no Add), or discard the workspace and return to staging
  • Git reset HEAD File nameCancel the temporary state, workspace contents remain unchanged, but the state changes to “not temporary”.

Git checkout — git checkout — git checkout — git checkout — git checkout Git checkout — git checkout — git checkout — git checkout

  • git reset --hard HEAD^Will fall back to the previous version
  • Git reset --hard the first few digits of a version numberRollback to the specified version

5. Branch management

  • Git branch dev creates a pointer to the current commit

  • Git checkout dev switches to the dev branch

  • Git checkout -b dev creates a new branch dev and switches to the dev branch. This is equivalent to two commands: git branch dev and git checkout dev

  • Git merge dev git merge dev git merge dev

  • Git branch -d dev Deletes the merged branch.

  • Git rebase master. If this command is executed in the current branch (non-master), the current branch is merged with the mater branch. This operation is similar to merge but has a different commit history.
