Nothing is more frustrating than wanting to do something and not knowing how to do it. In this How-to, we will be going over the some of FreeBSD’s more popular commands so we could make our lives easier and work more effective.
You need a FreeBSD server that is configured with a static IP address.
Hierarchy Manual in FreeBSD
In FreeBSD, sometimes it can be difficult to remember so many directories and what they contain. Similar to Linux systems there is a manual that you can bring up and refresh your memory and continue working on your task. This is the directory Hierarchy manual, and it can be view with the following command.

You could also remove files with the rm command. Copy and paste the following command replacing the brackets and myfile with the file that you want to remove or deleted.
