I made freedos but on terminal, for android users , termux

#termux #terminal #cmd #freedos

To run my freedos 1.1 copy this and past it in terminal:-
cat << 'EOF' > start-dos.sh

!/bin/bash

--- 1. Clean up old runs ---

pkill -f qemu-system-i386
pkill -f python
clear

--- 2. Menu ---

echo "================================================"
echo " FREEDOS SUPREME BOOT SELECTOR"
echo "================================================"
echo " 1) HD Character Engine (Half-Blocks + Color)"
echo " 2) Ncurses (Native Terminal Mode)"
echo " 3) VNC Server (Port 5900)"
echo " 4) NoVNC (Web Browser Mode)"
echo " 5) X11 Mode (Requires Termux:X11)"
echo "------------------------------------------------"
printf "Select Display Mode [1-5]: "
read mode

Ensure mode is trimmed

mode=$(echo $mode | tr -d '[:space:]')

--- 3. The HD Engine with Mouse & Touch Mapping ---
