# git diff
> Show changes to tracked files.
- 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}}`
- Create a patch file:
`git diff > {{target_file}}.patch`
- Compare a single file between two branches or commits:
`git diff {{branch_1}}..{{branch_2}} [--] {{path/to/file}}`
