• git log -p --stat - view both modified files and file chanegs
• git show <SHA id> - view file changes of specific SHA id
• git show SHAid --state - view modified files of specific SHA

• git add . - add all files in current directory to stage
• git add <file names with space as delimiter> - add specific files to stage
• git add -u - add all tracked files

• git commit -m <message> - write a commit message without using the text editor
  • Guideline: https://udacity.github.io/git-styleguide/
• git commit - write commit message with text editor opened
