In Unix, the first process is called init. All the others aredescendants of “init”. The init process spawns a sshd process thatdetects a new secure ssh requested connection (WKPort 22). Upon anew connection, sshd spawns a login process that then loads a shellon it when a user successfully logs into the system. Now, assumethat the user types
who | grep <uwnetid> | wc –l
Draw a process tree from init to those three commands. Add fork,exec, wait, and pipe system calls between any two processesaffecting each other.
