This course introduces you to the advanced features of the UNIX Bourne shell and teaches you how to apply them effectively. You will also learn new UNIX commands like sed and awk, which are commonly used in shell scripts.
This is the second in a two-part series that teaches UNIX shell programming. This course teaches you to use advanced features of the shell including embedded command execution, command line argument processing, debugging techniques, use of sed to edit files, and use of awk to format command output.
Along the way, you will work on a series of your own shell script projects that will let you put your new skills to work in common shell script tasks in an actual UNIX environment.
