Purpose

dysk is a linux utility listing your filesystems.

standard

Usage is shown in a graphical way.

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

By default, only the "normal" devices, the ones you're usually interested about, are shown, but you can see the other ones with the -a option.

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).

Tables

The default display of dysk is a table, which can be configured with the columns of your choice.

See Table for the definition of the columns and the syntax for choosing them, or on how to sort rows.

The table can also be exported in CSV.

JSON

dysk --json outputs the result as JSON which can be used for your own scripts or programs.
