A linux utility listing your filesystems.
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
```
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
```
To get the output as JSON, do `lfs -j` or `lfs -a -j`.
You may pass a path to have only the relevant device shown.
For example:
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.
