## Unreleased
### Added
- `--fix` mode - instead of outputting a shell script or text file, fif will rename the misnamed files for you!
- By default, the user will be prompted for each rename. This behaviour can be changed with the new `p`/`--prompt`
flag: `-p always` to be prompted each time (the default), `-p error` to be prompted on errors and when a file
would be overwritten by renaming, and `-p never` to disable prompting altogether - this behaves the same as
- By default, the user will be prompted only if fif encounters an error while renaming the file, or if renaming
the file would cause another file to be overwritten. This behaviour can be changed with the new `p`/`--prompt`
flag: `-p always` to be prompted each time, `-p error` to be prompted on errors and when a file would be
overwritten by renaming, and `-p never` to disable prompting altogether - this behaves the same as
answering "yes" to every prompt.
- The `--overwrite` flag must be specified along with `--fix` in order for fif to process renames that would cause an
existing file to be overwritten. Without it, fif will never overwrite existing files, even with `-p always`.
