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
  4. Change to cloned or extraction directory
  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 don't have bash-4.4# as prompt just #
  • Automatically creates .bash_history in root folder when you drop to a root shell so root shell history is preserved
  • Can be used like ordinary sudo (but only as root, no other user)
  • Can drop to root shell sudo su [-]
  • Runs built in Termux binaries and exteral binaries with optional arguments as root in current directory
  • Generates output in shell currently using
  • Can be used in other bash scripts
  • [option] Can turn off colored error messages be editing the variable colored at the beginning of sudo file
Usage:

sudo su [-]  
  Drop to root shell

sudo <command> [<args>]  
  Run command as root with optional arguments
