Basic Log

git log

It shows commits in reverse chronological order (newest first).

One-line Format

git log --oneline

Shows a compact view with the hash and message.

Graphical View

git log --graph --oneline --all

Shows branches and merges visually.

Filtering Logs

git log -n 5                    # Last 5 commits
git log --since="2 weeks ago"   # Recent commits
git log --author="Astronaut"    # By author
git log -- navigation.js        # For specific file

Detailed View

git log -p

Shows the diff for each commit.

Custom Formatting

git log --pretty=format:"%h - %an, %ar : %s"

Formats: %h (hash), %an (author), %ar (relative date), %s (subject).
