I want to know how many partitions are in my system and I used fdisk (found the command on google). The following came out, and I'm not too sure where it says how many partitions.

# fdisk -l

ok I did something else this time, but I still don't understand what it's saying:

cat /proc/partitions
major minor #blocks name

11 0 619520 sr0
8 0 20971520 sda
8 1 1024 sda1
8 2 512000 sda2
8 3 20456448 sda3
253 0 2064384 dm-0
253 1 18382848 dm-1

You could run:

df -h

This will show you the amout of free disk space of each partition on your system (the "-h" formats it to be a little easier to read).
This way you also get a list of all your partitions.

You can also view the contents of the fstab file.

cat /etc/fstab

This file lists your disk partitions and how they are configured.

Hello,

The first command you ran (fdisk -l) was perfect for showing the partitions and did give you the information about your drive. The tricky part is you are using some sort of virtual system and not seeing true disks. Your drive (/dev/sda) or device scsi disk a is a 21.5GB Hard disk and is partitioned into 2 partition (sda1 and vg_virtualcomputerelmo ) sda1 is the boot partition and vg_virtualcomputerelmo is a volume group containing 2 logical volumes (root or /, and the swap logical volumes). The commands vgdisplay and lvdisplay will show you the volume group and the logical volumes created in that volume group.
