git diff

Show changes to tracked files. More information: https://git-scm.com/docs/git-diff.

• Show unstaged, uncommitted changes:
  git diff
• Show all uncommitted changes (including staged ones):
  git diff HEAD
• Show only staged (added, but not yet committed) changes:
  git diff --staged
• Show changes from all commits since a given date/time (a date expression, e.g. "1 week 2 days" or an ISO date):
  git diff 'HEAD@{3 months|weeks|days|hours|seconds ago}'
• Show only names of changed files since a given commit:
  git diff --name-only {{commit}}
• Output a summary of file creations, renames and mode changes since a given commit:
  git diff --summary {{commit}}
• Compare a single file between two branches or commits:
  git diff {{branch_1}}..{{branch_2}} [--] {{path/to/file}}
• Compare different files from the current branch to other branch:
  git diff {{branch}}:{{path/to/file2}} {{path/to/file}}
