pfetch

A pretty system information tool written in POSIX sh.

The goal of this project is to implement a simple system information tool in POSIX sh using features built into the language itself (where possible).

The source code is highly documented and I hope it will act as a learning resource for POSIX sh and simple information detection across various different operating systems.

If anything in the source code is unclear or is lacking in its explanation, open an issue. Sometimes you get too close to something and you fail to see the "bigger picture"!

OS support

• Linux (A myriad of distributions)
• MacOS
• OpenBSD
• FreeBSD
• NetBSD
• Haiku

TODO

• Add optional and additional information detection.
  • CPU
  • Terminal Emulator
    • The way I implement this in neofetch is interesting.
  • Terminal colors
  • ???
• Expand operating system support.
  • Solaris
  • MINIX
  • AIX
  • IRIX
  • FreeMiNT
  • Windows
    • CYGWIN
    • MSYS
    • MINGW
    • WSL (this is fairly simple)

Configuration

pfetch is configured through environment variables.

Make pfetch update on an interval

This makes pfetch display interactively like htop/top.
