Important Git commands

git stash:

  • Explanation:

    • git stash temporarily saves changes that are not ready for commit. It's useful when you need to switch branches or deal with unexpected issues.
  • Usage Example:

      git stash  # Temporarily saves changes
    

git stash pop:

  • Explanation:

    • git stash pop applies the latest stash and removes it from the stash list. It's a convenient way to reapply changes after addressing other tasks.
  • Usage Example:

      git stash pop  # Applies the latest stash and removes it
    

git revert:

  • Explanation:

    • git revert creates a new commit that undoes the changes introduced by a specific commit. It's a safe way to undo changes without altering the project's commit history.
  • Usage Example:

      git revert <commit_hash>  # Creates a new commit to undo changes
    

git rebase:

  • Explanation:

    • git rebase is used to rewrite commit history. It moves, combines, or deletes commits, providing a cleaner and more linear history.
  • Usage Example:

      git rebase <base_branch>  # Rebases the current branch onto the specified branch
    

git reset:

  • Explanation:

    • git reset moves the branch pointer to a specific commit, discarding changes after that commit. It's a powerful command that should be used with caution.
  • Usage Example:

      git reset <commit_hash>  # Resets the branch to a specific commit
    

git clean:

  • Explanation:

    • git clean removes untracked files from the working directory. It helps keep your project clean by getting rid of files that aren't being tracked by Git.
  • Usage Example:

      git clean -n  # Shows a preview of files to be deleted
      git clean -f  # Deletes untracked files
    

git reflog:

  • Explanation:

    • git reflog shows a log of all changes to branch references, including resets and rebases. It helps recover lost commits or branches.
  • Usage Example:

      git reflog  # Shows a log of branch reference changes
    

Squash:

  • Explanation:

    • Squashing commits means combining multiple commits into a single commit. This is often done during an interactive rebase or when merging branches to create a cleaner and more concise history.
  • Usage Example:

    • Squashing commits during an interactive rebase:

        git rebase -i HEAD~<number_of_commits>
      
    • Marking commits with "squash" or "s" allows you to combine them.
