How To Get Linux Filesystems Information Using Dysk Utility

Dysk: A Superior Alternative to the df Command for Linux Filesystem Inspection

The df command is a common tool for examining Linux filesystems, showing used and available disk space. However, dysk offers a more detailed and user-friendly experience. This guide explains dysk, its features, installation on Linux, and its usage for retrieving filesystem information.

Introduction

A Linux filesystem organizes and manages files on a disk or partition. Understanding its structure is crucial for efficient system administration. While df is widely used, dysk provides a superior alternative.

What is dysk?

dysk (formerly 'lfs') is a command-line tool displaying detailed mounted disk information in Linux. It's considered an improvement over df -H. Key advantages include:

• Disk identification ("rem," "HDD," "SSD").
• Consistent use of SI units.
• Filesystem type display.
• Size-based filesystem sorting.
• Tabular output (unlike df's list format).

dysk is open-source and written in Rust.

Installing dysk on Linux

Installation is possible via Cargo or precompiled binaries.

Method 1: Using the Cargo Package Manager

Install Rust: If Rust isn't installed, install it first. (Instructions for installing Rust on Linux are readily available online).

Update Rust (if installed):

$ rustup update

Install dysk:

$ cargo install --locked dysk

Method 2: Using Precompiled Binaries

Download the Binary: Download the latest release from the dysk releases page. Replace x86_64-linux with your architecture if necessary.

$ wget https://dystroy.org/dysk/download/x86_64-linux/dysk

Add to $PATH: Move the executable to a directory in your $PATH (e.g., /usr/local/bin/).

$ sudo mv dysk /usr/local/bin/

Retrieving Linux Filesystem Information with dysk

Here are examples of using dysk:

Basic Overview:

$ dysk

This lists mounted disks, showing size, used space, free space, and usage percentage.

<code>┌──────────┬────┬────┬────┬─────────┬────┬────┬───────────┐
│filesystem│type│disk│used│   use   │free│size│mount point│
├──────────┼────┼────┼────┼─────────┼────┼────┼───────────┤
│/dev/sda6 │ext4│HDD │3.2G│10% ▌    │ 30G│ 34G│/home      │
│/dev/sda1 │ext4│HDD │7.1G│40% ██   │ 11G│ 18G│/          │
└──────────┴────┴────┴────┴─────────┴────┴────┴───────────┘</code>

Listing All Filesystems: Use the -a option:

$ dysk -a

Inode Information: Use -c inodes:

$ dysk -c  inodes

Custom Columns: Use -c to customize column order and selection. Refer to the dysk documentation for available columns.

Current Directory's Disk:

$ dysk .

Filtering: Use -f for filtering based on usage, free space, type, etc. (Examples provided in the original text).

Sorting: Use -s to sort by columns (e.g., -s free). Add -desc for descending order.

JSON Output: Use -j for JSON output.
