Introduction:

This is Go version of C library

Rootsh is a wrapper for a shell which will make a copy of everything printed on your terminal. Its main purpose is to give ordinary users a shell with root privileges while keeping an eye on what they type. This is accomplished by allowing them to execute rootsh via the sudo command. Unlike a simple "sudo -s" which is the usual way doing this, "sudo rootsh" will send their terminal keystrokes and output to a logfile and eventually to a remote syslog server, where they are out of reach and safe from manipulation.

Usage:
