Linux csh Scripting question?

Question

I am wanting a line I can add to a script file which will log the activity of the script file for later debugging purposes.

Answer 1

run in verbose mode.
set -v (do not remember exactly)

Answer 2

script foo.txt

... will open up a subshell and record all input and output to the named file (in this example "foo.txt").

The manpage says:

"Script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive session as proof of an assignment, as the typescript file can be printed out lat­er with lpr(1)."
