4. Ethical Hacking and Penetration Testing with Kali Linux - Updates and Gedit

What's Inside :
Inside this video , we are going to install gedit and we will also learn some basic commands of linux. We will start by learning how to install applications in linux and then we will learn how to get updates for the same.

The basic command to install any application on Linux is

sudo apt-get install gedit

Here sudo is used to install the application in root mode which is like an administrator mode in windows machine. Kali Linux is a single root user machine so sudo is not necessary in kali linux but if in case of other versions of linux like ubuntu , we must use the sudo command to get root access .

The second command that we are going to learn about is update any linux operating system. The command for the same is 

sudo apt-get update

this command will help us to update package list . This is necessary before upgrading the system. The next command is 

sudo apt-get upgrade

This command will fetch new versions of packages existing on the machine if APT knows about these new versions by the previous commands ( apt-get udpate )
