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).

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

You need the Rust tool chain.

cargo install lfs

lfs can be installed from the community repository:

pacman -S lfs

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:

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

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

Use lfs --help to list the other arguments.

If you want to display the same data in your Rust application, have a look at the lfs-core crate.
