Original Description

Description

This PR adds support for the Interix environment, also called "Windows Services for UNIX" or "Windows Subsystem for UNIX-based Applications", which was available from Windows NT 4.0 until Windows 8 and Server 2012.

I have followed the coding guidelines to the best of my abilities. All changes have passed shellcheck.

Features

This PR adds proper detection of the OS, Distro, Model, Kernel, Uptime, CPU, GPU, Memory, Battery, Packages and Battery. A colored logo has been added as well, based on this icon commonly used for the UNIX Subsystem

Example output:

Issues

dylanaraps#1822

TODO

The Interix implementations of bash and other UNIX like features are a bit quirky, causing the following issues:

• Random digits are printed before the logo is printed
• Shell and Terminal detection do not work reliably yet
• Disk detection does not work because df does not list a / mount point
• On Host and CPU sometimes white spaces are replaced with a ⌂ character

This is a migrated PR that adds support for Interix (Windows Subsystem for UNIX/SFU).

Interix/SFU was a deprecated Microsoft technology that has been replaced by WSL (Windows Subsystem for Linux). Given that:

1. Interix was discontinued with Windows 8.1
2. WSL is the modern replacement and is fully supported
3. No active Interix users are likely testing this

The changes in this PR are no longer relevant to modern Windows systems.

Closing as won't-merge. If you're using a legacy Interix system and would like to contribute a tested patch, please open a new PR.
