Linux System Information

Linux System Information Script

Copyright © 2019 Teal Dulcet

Simple script to quickly output system information on Linux, including:

• Linux distribution
• Computer Model
• Processor (CPU)
• CPU sockets/cores/threads
• CPU caches
• Architecture
• Total memory (RAM)
• Total swap space
• Disk space
• *Graphics Processor (GPU)
• Hostname (FQDN)
• IP address(es)
• MAC address(es)
• Time zone
• Language
• *Virtualization container
• *Virtual Machine (VM) hypervisor

* If present

RAM, swap and disk space is output in both MiB (1024² bytes) and MB (1000² bytes). Similar to the systeminfo command on Windows.

Requires at least Bash 4+. Compared to similar programs, this script outputs much more information and is smaller. Useful when using an unfamiliar system or VM, particularly before running a program that has specific system requirements. All the values are saved to variables, which makes this easy to incorporate into larger scripts.

Usage

Supports all modern Linux distributions and the Windows Subsystem for Linux (WSL).

wget

wget -qO - https://raw.github.com/tdulcet/Linux-System-Information/master/info.sh | bash -s

curl

curl -sL https://raw.github.com/tdulcet/Linux-System-Information/master/info.sh | bash -s

Example Output

Ubuntu Desktop

Ubuntu Server

openSUSE Server

Raspberry Pi OS (Raspbian)

Google Cloud Platform (Debian)

Scripts where this is incorporated

• Linux Distributed Computing Scripts
• Mail-in-a-Box (pending)
• ispconfig_setup

Other Scripts

Datatype Information

Outputs C/C++ datatype information, including datatype sizes, minimum values, maximum values, etc. for the current system. Requires C++11. Supports both Linux and macOS.

wget -qO - https://raw.github.com/tdulcet/Linux-System-Information/master/typeinfo.sh | bash -s

Public IP addresses

Outputs your public IP addresses using a couple dozen different services to find the one with the best HTTPS response times on your network.

wget -qO - https://raw.github.com/tdulcet/Linux-System-Information/master/ipinfo.sh | bash -s

Other System Information Scripts

• neofetch (Supports multiple operating systems and Linux distributions, lots of command line options, outputs an ASCII version of the logo for a hard coded set of operating systems, but slow to run, displays less information, many of the features require external dependencies, a display and that it is run directly on the system and many of the features are disabled by default)
  • Test with this command:

wget -qO - https://raw.github.com/dylanaraps/neofetch/master/neofetch | bash -s -- -v --no_config

• screenFetch (Supports multiple Linux distributions, lots of command line options, outputs an ASCII version of the logo for a hard coded set of distributions, but extremely slow to run and displays less information and many of the features require a display and that it is run directly on the system)
  • Test with this command:

wget -qO - https://raw.github.com/KittyKatt/screenFetch/master/screenfetch-dev | bash -s -- -v

• system-report-card (Only shows total RAM, swap and disk space)
