fet.sh

a fetch written in POSIX shell with no external commands

Arch: fet.sh-git (AUR)
Gentoo: app-misc/fetsh (GURU overlay)
KISS: fetsh (Community)
Nix: fet-sh (nixpkgs-unstable)
Alternatively, copy fet.sh to somewhere in $PATH and mark it as executable (chmod +x fet.sh)

fet.sh has a few basic configuration options using environment variables, for example:

$ info='n os wm sh n' fet.sh

Supported options are:

• accent (0-7)
• info
• separator
• colourblocks

For less trivial configuration I recommend editing the script, I tried to keep it simple.

MacOS, BSD, and Android don't show much info.
