To install Linux on a USB flash drive, you need a drive of at least 8 GB. Note that the speed of some flash drives isn’t quite adequate for running a live Linux OS. Performance improvements can be substantial if you use a flash drive with faster read and write speeds. For the best results, a flash drive with a minimum of 15 MB/second read and write speed is recommended. You can check Web sites such as http://usb/userbenchmark.com/ for performance benchmarks to help you choose a suitable drive within your budget.
Once you find the proper flash drive, you’ll find up-to-date USB installation instructions
on the Kali Linux Web site (http://docs.kali.org/downloading/kali-linux-live-usb-install).
There are instructions for those using Windows, Linux, or Mac OS X. These instructions
walk you through downloading Kali Linux to booting into Kali Linux for the first time.
It’s important to make sure your software is up-to-date, so be sure to run the apt-get
update and apt-get upgrade commands, which check the Kali Linux repositories for
updates.
Installing New Software
Because Kali is an Ubuntu Linux distribution, thousands of free programs are available that
you can download and install with just a few simple commands. These programs, which are
specific to an OS version, are stored on Internet archives called repositories. To install new
software, you can simply use the command apt-get install packagename (replacing
packagename with the name of the software package you want to install). If you don’t
know the software package name, just use a search engine to look it up!
