fetchit

fetchit is a terminal-based system information viewer written in C++. It works like neofetch/fastfetch and consists of a single file (main.cpp).

Features

• Displays distro, kernel, uptime, shell, CPU, GPU, RAM, and OS date information.
• Detects distro name via /etc/os-release.
• Shows ASCII logos for supported distros.
• Reads /usr/share/hwdata/pci.ids for GPU names; prints hex IDs if missing.
• Accounts for Unicode character width (for icon alignment).

Supported Distro Logos

arch, cachyos, debian, ubuntu, fedora, manjaro, opensuse, pop, linuxmint, endeavouros, void, alpine

Requirements

• Linux
• A C++17-capable compiler (e.g., g++)
• A UTF-8 terminal with ANSI color support (for icons and colors)
• The following files/paths are read:
  • /etc/os-release
  • /etc/hostname
  • /proc/uptime
  • /proc/cpuinfo
  • /proc/meminfo
  • /sys/bus/pci/devices/
  • /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
  • /usr/share/hwdata/pci.ids (optional)

Build

g++ -std=c++17 -O2 -o fetchit main.cpp

Run

./fetchit

Notes

• OS Date is based on the creation time of /etc/hostname.
• If no ASCII logo is found, only the info list is printed.
• The distro logo is displayed in color via ANSI escape codes.
• This tool targets Linux systems and is not expected to work on non-Linux OSes.
