One of the great strengths of the Unix system is the collection of utilities that have been created over the lifetime of Unix. Rather than using a large single multipurpose application, the Unix style of command usage is to create limited purpose commands and then string them together with pipes and redirection and/or invoke them from batch shell scripts to create the "tool" for the job at hand.
The following is a survey of some the more common commands available. This is not exhaustive, either in number of commands covered or the depth of coverage. Some commands will be explored in a little more detail. Some will only be briefly described. And some of these commands will be covered in more detail in other modules of this class. As always, feel free to read through the man and info pages. And email your instructor with any questions you have.
For commands that are primarily covered here, try the exercises presented.
