A linux utility listing your filesystems.

![screenshot](doc/screenshot.png)

Besides traditional columns, the `disk` column helps you identify your "disk" (or the mapping standing between your filesystem and the physical device) :

* `remov` : a removable device (such as an USB key)
* `HDD` : a rotational disk
* `SSD` : a solid state storage device
* `RAM` : an in-memory device (such as zram)
* `LVM` : a device mapped to one or several disks using LVM
* `crypt` : a crypted disk

All sizes are normally based on the current SI recommendations (1M is one million bytes) but can be changed with `--units binary` (then 1M is 1,048,576 bytes).

## Installation

### Precompiled binary

You can download it from https://github.com/Canop/lfs/releases

### From source

You need the [Rust tool chain](https://rustup.rs/).

```
cargo install lfs
```

### Arch Linux

**lfs** can be installed from the [community repository](https://archlinux.org/packages/community/x86_64/lfs/):

```
pacman -S lfs
```

## Usage

```
lfs
```

### All filesystems

By default, **lfs** only shows mount points backed by normal block devices, which are usually the "storage" filesystems you're interested into.

To show them all, use

```
lfs -a
```

### JSON

To get the output as JSON, do `lfs -j` or  `lfs -a -j`.

### Find the filesystem you're interested into

You may pass a path to have only the relevant device shown.
For example:

![lfs dot](doc/lfs-dot.png)

### Show labels

Labels aren't frequently defined, or useful, so they're not displayed by default.

Use `--labels` or `-l` to display them in the table:

![labels](doc/labels.png)

### Other options

Use `lfs --help` to list the other arguments.

## Internals

If you want to display the same data in your Rust application, have a look at the [lfs-core](https://docs.rs/lfs-core/) crate.
