df command and free/available space.

[techlists at phpcoderusa.com]

Hi,

I've gotten VirtualBox working and installed just the Ubuntu plain 
server 20.04 with the goal of creating a LAMP setup that will be used 
for a tiny bit of PHP testing.

I allocated 10GB of space for this VM instance.

I want to allocate a limited amount of disk space because I think this 
is static and will count as disk usage on the host even when my virtual 
machine is not running.

I ran "df -h" and here is the output:

I assume the line :  "/dev/mapper/ubuntu--vg-ubuntu--lv  8.1G  3.6G  
4.0G  48% /" is root.

So a minimal install of the Ubuntu server 20.04lts is 3.6G?  Yikes is 
this correct?  So I have 4G free?  I can live with 4G free.  Yikes I 
have yet to install PHP/MySql/Apache.

Is this correct?

Thank you for your input!!
