fif
===
A command-line tool for detecting and optionally correcting files with incorrect extensions.

## Installation
```bash
cargo install --locked fif
```

## Usage
See `fif --help` for more.

### The basics
The simplest way to use fif looks like this:
```bash
fif -E images ~/Pictures
```

This command will scan all of the files with extensions used by image files (.jpg, .png, etc) in your `~/Pictures`
directory.

You can also manually specify a set of extensions to use:

```bash
fif -e jpeg,jpg,zip,docx ~/Documents
```

By default, fif will output a bash script that can be used to fix all the files it found with incorrect file extensions.
You might find it useful to output this script to a file (rather than to stdout):

```bash
fif -E images ~/Pictures > output.sh
```
