My super-quick-to-setup Termux environment.

pkg install -y wget
bash -c "$(wget https://bit.ly/2Slw2KX -O -)"
# bash -c "$(wget https://raw.githubusercontent.com/fabiospampinato/termux-env/master/install.sh -O -)"

• Immersive mode: it might be a good idea to force Termux to go fullscreen, in order to have more screen real estate:
  • Enable: adb shell settings put global policy_control immersive.full=com.termux
  • Disable: adb shell settings put global policy_control immersive.off=com.termux
