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"!

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 (#5)
- MINIX (#6)
- AIX (#7)
- IRIX (#8)
- FreeMiNT (#9)
- Windows (#10)
  - CYGWIN
  - MSYS
  - MINGW
  - WSL (this is fairly simple)

ufetch: Lots of ASCII logos.
- Contrary to the belief of a certain youtuber, pfetch shares zero code with ufetch. Only some of the ASCII logos were used.
