I am developing x-cmd.
Demo website: https://x-cmd.com Code is here: https://github.com/x-cmd/x-cmd
I have spent 3 years on this project. A lot of important modules using sh/awk are introduced, like json parser module, tui module, which make implementing rich but lightweight cli with sh/awk/curl possible.
X-cmd also providing a pkg system with 500+ pkgs. No root priviledge required when installing x-cmd and x-cmd's pkg.
