Summary

In this chapter we showed how to write out a file using the redirection operator and how to read a file using the (properly formatted) read command. Converting the contents of a file into a variable was covered as was the use of checksums and file encryption.

In the next chapter we will look at some utilities that can be used to gather information from web pages on the Internet.
