To view the output of and findings by bulk_extractor, we can also display a list of directories within the Terminal by typing ls -l. We can see that the bulk_output folder has been created by bulk_extractor:

We can now list the contents of our output folder (bulk_output) by typing ls -l bulk_output:

The url.txt file reveals many websites and links visited:

While this was a simple exercise done with a small evidence file, be sure to have a look at the many others available at http://digitalcorpora.org/ and see what bulk_extractor reveals.
