Git Commit πŸ“

Committing changes is a crucial step in version control. Here are some useful Git commit commands:

  • git commit -m "<message>"

    • Commit changes with a specified message.
  • git commit -a -m "<message>"

    • Commit changes with a message and add all files to the staging area.
    • This is a shortcut to combine staging and committing for modified files.
  • git commit -am "<message>"

    • Another shortcut to commit changes with a message and add all files to the staging area.
    • A concise way to streamline the commit process for modified files.

These commands help you effectively record and save changes in your Git repository. Choose the one that fits your workflow! πŸš€

    • Create a new branch with the specified name.
  • git branch -M <branch-name>

    • Rename the current branch to the specified name.
  • git branch -d <branch-name>

    • Delete a branch. Use caution, as this permanently removes the branch.
  • git branch -m <old-branch-name> <new-branch-name>

    • Rename a branch from the old name to the new name.
  • git branch

    • List all the branches in the local repository.

  • git remote set-url <remote-name> <new-url>

    • Change the URL of an existing remote repository.

Utilize these commands to manage your interactions with remote repositories effectively. Happy collaborating! 🌐

Git Push πŸš€

The git push command is vital for publishing your local changes to a remote repository on GitHub. Here are some useful variations:

  • git push

    • Push the local repository to the remote repository on GitHub and set the default branch to the current branch.
  • git push <remote-name> <branch-name>

    • Push the local repository to the remote repository on GitHub for the specified branch.
  • git push -u <remote-name> <branch-name>

    • Push the local repository to the remote repository on GitHub and set the default branch to the specified branch.
  • git push --set-upstream origin <branch-name>

    • Push the local repository to the remote repository on GitHub and set the default branch to the specified branch.
  • git push --all

    • Push all branches to the remote repository on GitHub.

  • git checkout <branch-name>

    • Switch to the specified branch.
  • git checkout -b <branch-name>

    • Create a new branch and switch to it.
  • git checkout -

    • Switch to the previous branch. This is useful for toggling between two branches.
  • git checkout -

    • Apologies for the confusion, but there's no direct command to switch to the next branch using git checkout. To navigate to the next branch, you can use the following:

      git checkout -

      This command will toggle between the current and previous branches, effectively moving back and forth.

Utilize these commands to seamlessly switch between branches in your Git workflow. Happy branching! 🌿

Git Clean 🧹

The git clean command is used to remove untracked files and directories from your local repository. Here are some variations:

  • git clean -f

    • Remove untracked files.
  • git clean -f -d

    • Remove untracked files and directories.
  • git clean -f -x

    • Remove untracked files and directories that are ignored by Git.
  • git clean -f -x -d

    • Remove untracked files, directories, and files that are ignored by Git.
  • git clean -f -x -e <file-name>

    • Remove untracked files, directories, and files that are ignored by Git, except for the specified file.
  • git clean -f -x -e <file-name> -n

    • Display the files that would be removed, but do not remove them from the local repository.

Ensure caution when using these commands, especially with the -f flag, as it forcefully removes files. Double-check the files to be removed before executing. Happy cleaning! 🧹

    • Check your global email.

These commands help personalize your Git experience and associate your commits with the correct user details. Happy configuring! πŸ‘€

Git Ignore 🚫

If you have files you don't want Git to track, using a .gitignore file is the solution. Here's a comprehensive guide to help you set it up:

  1. Create a .gitignore File:

    • In the root directory of your Git repository, create a file named .gitignore.
  2. Edit the .gitignore File:

    • Open the .gitignore file in a text editor.

    • Add the names of files, directories, or patterns you want Git to ignore. Each entry should be on a new line.

      For example, a basic .gitignore file might look like this:

      # Ignore compiled files
      *.class
      
      # Ignore log files
      *.log
      
      # Ignore build directories
      target/
      
  3. Save and Commit:

    • Save the .gitignore file.
    • Commit the .gitignore file to your repository.

This ensures that Git excludes specified files and directories from version control, maintaining a clean and focused repository. Happy coding! πŸ§ΉπŸš€
