Here's a single-file, mobile-responsive "WebOS Shell Terminal" with all code inline (vanilla HTML/CSS/JS, no dependencies). It simulates a tiny filesystem (persisted in localStorage), supports command history, tab-completion, basic Unix-like commands (help, ls, cd, mkdir, touch, cat, echo with > and >>, rm, mv, cp, pwd, clear, date, uname, whoami, history), and a clean terminal UI that works great on phones and desktops. > Copy everything into a file named `webos-terminal.html` and open it in your browser. ```html WebOS Shell Terminal

Tip: Tab to autocomplete History: ? / ? Clear: clear Persisted with localStorage
