What is Termux Sudo and it's Installation

Termux Sudo

A bash script that provides sudo for Termux

Termux is a terminal emulator and Linux environment for Android

Note

termux-sudo was originally hosted on GitHub.

Due to the fact that Microsoft is purchasing GitHub, I have decided to move it here.

Requirements

Rooted phone with su binary
SUDO WILL NOT WORK WITHOUT SU

Installing sudo

• 1.Clone termux-sudo or download to phone and extract
• 2.Open Termux
• 3.Install a dependency needed for sudo:

 $pkg install ncurses-utils

• 5.Execute the following commands to place sudo into the correct directory with the proper permissions and ownership

cat sudo > /data/data/com.termux/files/usr/bin/sudo

chmod 700 /data/data/com.termux/files/usr/bin/sudo

Features

• Sets up its environment automatically on first run, no need to do anything but use it
• Creates a root folder .suroot in the Termux home folder with proper root permissions and ownership
• Creates .bashrc file in root folder with proper PATH and LD_LIBRARY_PATH variables set so all binaries function correctly
• Bash prompt PS1 variable is also set so you dont have bash-4.4# as prompt just #
