GIT GIT

  • Git init creates a git directory in the current directory, and the current directory becomes a Git repository.

  • Git clone Git repository URL: Copy the HTTP or SSH link to a local git repository.

  • Git add file: Adds a file to the cache that is marked as tracked.

  • Git add. : Caches all files in the current directory, excluding deleted files. Git add only copies the current version of the file to the cache. If you do not git add it again, you will only commit the last git add cache to the repository.

  • Git commit -m “Commit this time” : Commit all file changes in the cache to the current branch of the repository at once.

  • Git commit-am: automatically cache all traced files and submit them to the repository. Often used to skip the Git add step and commit quickly.

  • Git commit –amend “commit now” : commit again. This submission replaces the results of the previous submission. This is especially useful when several files have not been added or the submission information has been incorrectly written. Git add is workspace -> cache, git commit is cache -> repository.

  • Git status: Displays the current status of the repository.

  • Git status -s: a brief introduction to the current status of the repository.

  • Git diff: Compares workspace and cache.

  • Git diff –cached: Compares the difference between a cache and a repository.

  • Git diff files: Compare the difference between a specified file in the workspace and in the cache.

  • Git diff file –cached: Compares the difference between a specified file in the cache and in the repository.

  • Git show: Look at the last commit.

  • Git show HEAD~1: check the penultimate commit.

  • Git show Commit version number: view the specified commit.

  • View staging area commit git ls-files

    • –cached (-c) View files in the staging area. Git ls-files is used by default
    • –midified (-m) View the modified file
    • –delete (-d) View deleted files
    • –other (-o) View files that are not tracked by Git
    • –stage (-s) displays the mode and the Blob object corresponding to the file, so we can retrieve the contents of the file in the staging area.

  • Git rm file: Delete the file from the repository and no longer trace it.

  • Git rm -f: An error occurs when you use git rm to delete a file from the staging area. You can run this command to forcibly delete the file from the cache and version library.

  • Git rm –cached file: Deletes the file from the repository, but leaves it in the workspace and untraceable by Git. This is usually done after an RM file is added to the.gitignore.

  • Git checkout — file: discard workspace changes. This file must be tracked by Git.

  • Git reset HEAD: Discard changes in the cache and roll back to the workspace.

  • Git reset –hard: Resets all files to the last commit state.

  • Git reset –hard HEAD~1: resets the current branch to the second-to-last version.

  • Git reset –hard Commit version number: resets the current branch to the specified version.

  • Git log: Displays commit logs from most recent to most distant. Contains the SHA1 checksum for each submission, the author’s name and email address, the submission time, and submission instructions.
