dysk – A Powerful Yet Simple Filesystem Overview Tool

Purpose

dysk is a lightweight but powerful Linux tool designed to display your filesystems in a clean, visual format. Unlike traditional commands, it simplifies identification by including a disk column that tags each mount point by its underlying storage type—whether it's an HDD, SSD, removable media, encrypted device, LVM, or even RAM-based 🌩️

Table Display

By default, dysk shows a neatly formatted table with common columns:

filesystem, type, disk, used, free, size, mount
Plus a simple graphical bar view for usage
You can:

Run dysk --list-cols to view all ~18 available columns (like inode counts, customizable stats).

Use -c or --cols to choose which columns to display (e.g., dysk -c label+use+size+disk+mount) dystroy.org.

Sort results by any column via -s or --sort (e.g., dysk -s free-desc) .

Export as CSV with --csv (and filter/sort using -f, -c) for scripting convenience dystroy.org.

JSON Output

Need to integrate with scripts or APIs? Just run dysk --json for machine-readable output—perfect for automation and custom workflows .

Filtering

Advanced usage lets you filter directly in the command line, like -f 'size>100G' to list only volumes larger than 100 GB. You can even output filtered CSV with those filters intact .

Installation

Precompiled binaries for various architectures (x86-64, ARM, etc.) are available—typically uploaded with each release (latest binaries date from May 14, 2025) .

Install via Rust’s Cargo: (Make sure Rust and build tools are up to date.) dystroy.org

1cargo install --locked dysk

Compile from source or use community-maintained package repos if preferred .

Why You’ll Love It

Visual clarity: Graphical usage bars plus a “disk type” column streamline quick understanding.
Customizable: Tailor columns, sorting, and output formats to your needs.
Script-friendly: JSON and CSV support makes it ideal for automation.
Lightweight and focused: No bulky dependencies—just a neat, efficient tool.

Quickstart Example

1# Display all main filesystem info with graphical bars 
2dysk 
3# Show only label, usage, total size, and disk type 
4dysk -c label+use+size+disk+mount 
5# Sort by free space, largest first 
6dysk -s free-desc 
7# List volumes over 100 GB, excluding remote filesystems, output CSV 
8dysk --csv -f 'size>100G and remote=false' > volumes.csv

In Summary

dysk is a modern replacement for commands like df and lsblk, offering:

Better visuals (usage bars, type tags)
Highly customizable output (columns, filters, formats)
Developer-friendly formats (JSON & CSV)
Easy installation via binaries or Rust

If you want a clear, scriptable snapshot of your filesystems—across HDD, SSD, removable media, LVM, and encrypted volumes—dysk is a smart, efficient choice.
