It's a good article but there are much easier ways to use binwalk than presented here.

In the first example he uses the "--signature" and "--term" flags, these are unnecessary. Running binwalk with no flags will produce the same output.

To extract part of the file, he also uses dd with the "skip" and "count" options painfully calculated. You can just use:

binwalk --dd='.*' img.bin

and it will extract everything that matches the pattern - the pattern above will extract all found files.

Just a quick note to be careful extracting what binwalk considers to be 'everything' (such as the pattern above, or a -e for known file types) on larger files. Sometimes there will be a higher amount of matches than you might expect (such as in a .pcap file). You could magically extract gigabytes of data from a 100MB file, which may be unhelpful and takes a long time.
