• Create a git repository: git init
• Add files to the repository: git add [filename or "--all"]
• Committing the added files: git commit
• Branches:
  • Creating a branch (current branch won't change - you'll have to perform a checkout after having created the new branch): git branch [name of new branch] [source branch]
  • Check in which branch I am: git branch
  • Check out a branch (!!TO AVOID COMPLICATIONS CHECK FIRST WITH git status THAT YOU HAVE NOTHING UN-ADDED OR UNCOMMITTED IN THE CURRENT BRANCH!!): git checkout [target branch]
  • Merge a source branch into a target one:
    • Check (with "git status") that you have nothing un-added or uncommitted in both source and target branches.
    • Check out the target branch.
    • git merge [source branch]
• Tags:
  • "Annotated" tags:
    • Create an annotated tag:
      git tag -a v0.1 -m "Initial prototype"
    • List tags:
      git tag
    • Show the comment of the annotated tag:
      git show v0.1
  • "lightweight" tags:
    • Create the lightweight tag:
      git tag v0.1
  • Roll back to a specific tag:
    git reset --hard v0.1
     
• Delete a file from GIT's history: git filter-repo --invert-paths --path <path to the file or directory>
