Updating Backtrack 5
Since Backtrack is based on Ubuntu 10.04 (which is based on Debian), it has the apt-get command. Apt-get is a powerful command-line tool that is used for installing new software packages, updating, and even upgrading the operating system. We will use this command to get the latest version of Backtrack. After logging in to Backtrack, open a terminal (Applications > Accessories > Terminal):
Then issue the following command:
root@bt:~# apt-get update && apt-get upgrade && apt-get dist-upgrade
If you just installed Backtrack, this update will take about 15-20 minutes. Keep an eye on the console for when it asks “Do you want to continue?”. Again, press ‘y’ for yes. You will want to run the command apt-get upgrade && apt-get upgrade once a week to keep Backtrack up-to-date.
There are many Linux commands, and they can be used in various combinations. I will list a the basic ones which you should learn if you are new to Linux and Backtrack. Most commands can have parameters which gives them added functionality. To see the parameters, or to learn what a command does, add -h or –help after them.
(Example: cat –help).
cat – This is command is short for “Concatenate” and prints out the standard output
Example: cat filename
cd – Change Director. Switches the current directory you are in.
Example: cd foldername
Example: cd root/Desktop/
clear – clears the terminal screen.
ls – List the files and folders within the current directory. (Note that is ‘L’ not ‘i’)
mkdir – Make Directory. Create a new directory of the given name
Example: mkdir myFolder
ping – Send a packet to a host and waits for a response.
Example: ping -c 4 google.com (The -c 4 parameter limits the ping to 4 counts).
rm – Remove. Removes a file or folder.
Example: rm filename
