The chapters in this part of the book deal exclusively with the CLI. Most CLI commands must have a process/thread focus for what they do. See Chapter 23, "Group, Process, and Thread Control" for more information.
You can use CLI commands without knowing much about Tcl, which is the approach taken in this chapter. This chapter tells you how to enter CLI commands and how the CLI and TotalView interact with one another when used in a nongraphical way.
While you can use the CLI as a stand-alone debugger, using the GUI is usually easier. You will most often use the CLI when you need to debug programs using very slow communication lines or when you need to create debugging functions that are unique to your program. This chapter presents a few Tcl macros in which CLI commands are embedded.
Most of these examples are simple, designed to give you a feel for what you can do.
