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

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

### Other backends
`fif` supports using [infer](https://crates.io/crates/infer) or [xdg-mime](https://crates.io/crates/xdg-mime) as its
backend for looking up file types. By default, xdg-mime will be used on Linux, and infer on all other systems.

xdg-mime should work on any Unixy system with [libmagic/file(1)](https://www.darwinsys.com/file/) installed, although
I've only tested it on Linux. infer should work on any system.

You can override the default backend for your system at compile time like so:

```bash
# xdg-mime
cargo install --features=xdg-mime-backend
# infer
cargo install --features=infer-backend
```

## 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
```

More coming soon!
