Introduction to Parrot OS (Putty), basic command line.

 As the first step, I install Parrot OS from the official website . I choose the version Parrot Security MATE ISO (default), it is a big iso but because I do not have problems with space in our lab so it wasn't a problem for me. 

Also for commodity, I installed this O.S. into an old desktop HP with an SSD just for testing purposes. 

IMPORTANT: As already we can read in putty this Operation System does not have any warranty, so please be aware of this before you decide to implement on your infrastructure or to any kind of deployment. 

As you can see I log in as root user, now I will perform some basic commands. 

apt update

apt upgrade

To be aware about apt upgrade

 So I recommend this upgrade command: 

apt full-upgrade

(Before you begin this, you may want to consider that can take a couple of minutes) 

 Done with the upgrade 

Now we can check our ports and our own ip address, with this command:



To see also how much ram we have and how much we actually use, we should use this command: 

free -m

 Now is time to have a look into the disks, so we will use the command

fdisk -l
