This script begins by loading and interpreting the make_actions.tcl file, which was described in Chapter 17, “Seeing the CLI at Work” . It then loads the fork_loop executable, sets its default startup arguments, and steps one source-level statement.

If you stored this in a file named fork_loop.tvd, you can tell TotalView to start the CLI and execute this file by entering the following command:

The following example places a similar set of commands in a file that you invoke from the shell:

The only real difference between the last two examples is the first few lines in the file. In this second example, the shell ignores the backslash continuation character; Tcl processes it. This means that the shell executes the exec command while Tcl will ignore it.
