Now, let's find out how a process accesses other processes.
Let's consider that the
vsftpd process is running; if it's not started, we can start it using the following command:
systemctl start vsftpd
vsftpd process is started by the
systemd process; this is a replacement of the
Sys V init process and runs within a context of
ps -eZ | grep init

So, here's the
systemd process ...
