Setting up git in your device

git config --global user.name <your-username>

git config --global user.email <your-email>

git config --global user.signingKey <keyID>
    • --global: The configuration applies to all repositories for the current user.
    • --local: The configuration applies only to the current repository.
    • --system: The configuration applies to all users on the system.
    • user.name & user.email define the author’s identity for commits.
    • user.signingKey specifies the GPG key ID used for signing commits and tags.

To display all the current configurations:

git config --list

To display the specific configurations:

git config --global user.name
git config --global user.email

Enable commit signing:

git config --global commit.gpgSign true

After enabling this, every commit will be automatically signed without needing the -S flag.

Disable commit signing:

git config --global --unset commit.gpgSign

General Use Cases:

  1. Staging the changes:
git add filename.ext
  • -A will select all the changes in the current directory. (Not a good practice, unless you know what you are doing)
  • -i for interactive picking the changes. (Useful for handling large changes)
  1. Committing the changes:
git commit -S -am "commit message"
  • -S - Signs the commit with your GPG key.
  • -a - Stages all modified and deleted tracked files (but not new files).
  • -m - Allows entering the commit message inline.
  1. Pushing the Changes:
git push <remote> <branch>
  • <remote> - The name of the remote repository (e.g., origin).
# find the remote repository name by
git remote -v
  • <branch> - The name of the branch to push (e.g., main or feature-branch).
# find the available or current branch by
git branch
  1. Show the commits:
git log --oneline --decorate --graph
  • --oneline - shows the commit in single line without any verbose output.
  • --decorate - use pretty printing (with colors!)
  • --graph - displays the commit messages in graph format. (easily understandable)
