In Linux, the first process is called init. All the others are descendants of init. The init process spawns a sshd process that detects a new ssh connection. Upon a new connection, sshd spawns a login process that then overloads a shell on it when a user successfully log in the system. Now, assume that the user types

who $C{P}_p$ gandalf $w{w}_{{?}_{?}}(-1)$

Draw a process tree from init to those three commands.

Add fork, exec, wait, dup$2$ and pipe system calls between any two processes affecting each other.
