How To Gather Comprehensive Disk Information On Linux

Mastering Linux system disk configuration and health is critical to system management, troubleshooting, and optimization. This article will introduce in detail how to use common tools such as parted, inxi and lsblk to display or to collect comprehensive disk information on Linux systems. After reading this article, you will have a clear understanding of how to collect and analyze disk data, which is very useful for maintaining and optimizing your Linux environment.

Let's get started!

Step Guide to Collecting Disk Information on Linux System

1. Prepare the output file

The first step is to create a text file to store all disk information. This file will be located in your home directory and is named

.

diskinfo.txt

This command initializes the

echo —PARTED 磁盘信息— > /home/$USER/diskinfo.txt 2>&1

file and adds a title at the beginning of the file to indicate that the following information is related to the disk partition.

diskinfo.txt2. List disk partitions using parted

Next, we use the

utility to list all disk partitions on the system. This command requires superuser permissions, so we use

. parted sudo

The output of this command is appended to the

sudo parted -ls >> /home/$USER/diskinfo.txt 2>&1

file, providing detailed information about each disk partition.

diskinfo.txt3. Use inxi to collect disk information

Utility is a powerful tool for collecting system information, including detailed disk data. We append the output of

to our inxi file. inxi diskinfo.txt

This command not only provides disk information, but also includes detailed information about processes, system resources, etc.

echo —INXI 磁盘信息— >> /home/$USER/diskinfo.txt 2>&1
sudo inxi -DpRjlLoux >> /home/$USER/diskinfo.txt 2>&1

4. List block devices using lsblk

Finally, we use the

utility to list block devices, including detailed file system and permission information.

lsblk

This command appends block device information to our

echo —LSBLK 磁盘信息— >> /home/$USER/diskinfo.txt
sudo lsblk -fm >> /home/$USER/diskinfo.txt 2>&1

file to complete the collection process.

diskinfo.txtAnalyze the collected data

After the

file is generated, you can open it with any text editor to analyze disk information.

diskinfo.txtThe file will contain parts marked with the title, such as "—PARTED disk information—", "—INXI disk information—" and "—LSBLK disk information—".

Each section provides a different perspective on disk configuration, allowing you to cross-reference and validate data.

The following is an example of the output of the diskinfo.txt file in my Debian 12 system: (The actual output will be omitted here, because this part will vary from system to system)

Use scripts to automate the collection of disk information

The following is a Bash script that uses parted, inxi and lsblk utilities to automate the process of collecting disk information.

The script prompts the user to choose whether to save the output to a file or display it in standard output.

It also checks if the required command is installed and if the command is missing, it provides installation instructions.

(Script: diskinfo.sh -- The script content is omitted here because it is the same as the original text)

How to use scripts to display or save disk information in files

Copy the above script to a file named diskinfo.sh.

Run the following command to make the script executable:

echo —PARTED 磁盘信息— > /home/$USER/diskinfo.txt 2>&1

Execute the script by running the following command:

sudo parted -ls >> /home/$USER/diskinfo.txt 2>&1

This script will save the extended disk information in a text file named diskinfo.txt in your home directory.

You can also move the script to the system's PATH and execute it from anywhere. Common options include /usr/local/bin or /usr/bin. For example:

echo —INXI 磁盘信息— >> /home/$USER/diskinfo.txt 2>&1
sudo inxi -DpRjlLoux >> /home/$USER/diskinfo.txt 2>&1

Restart the current shell session or log out and log in again. From now on, you can simply run the diskinfo command from anywhere to display comprehensive information about the disk.

Summary

Collection of comprehensive disk information on Linux systems is a basic task for system administrators and developers.

In this guide, we learned how to use the parted, inxi, and lsblk utilities to collect disk information in Linux in step by step. These utilities will help you effectively collect and analyze disk data, ensuring your system runs at its best.

We also created a simple Bash script to automate this process. This script contains more powerful error handling and checking, ensuring it correctly identifies installed commands and provides useful installation instructions if any commands are missing.
