This chapter introduced the command-line shell, considered by many to be the heart of Linux. We've discussed its similarities to MS-DOS, and shown that these are only cursory; knowledge of DOS doesn't equate to skill within BASH. In the long run, you should work to polish your BASH skills.
This chapter also introduced some elementary commands used within BASH, such as those used to provide directory listings and to copy files. We looked at how command-line options can be used to control BASH tools. In many cases, these are mandatory, so you learned how the BASH shell itself can be used to investigate a command and find out vital information about how it works.
At this point, your newfound knowledge will have no doubt caused you to venture into the SUSE Linux file system itself, which can be a confusing, if not terrifying, place for the inexperienced. But don't worry. The next chapter explains everything you need to know about the file system and what you'll find in it.
