open your terminal and issue: "csh -i | tee nameoffile"

what does that mean?
well .. youll get a new prompt and everything that goes on, on that propmt,  
will be piped to "tee" which will "record everything" on "nameoffile" 

When done, press Ctrl-D
then "cat nameoffile" to view your session.

Example:

"zcat" or "zmore" to view it.

That's way better to store just the error messages (which can be easily 
redirected STDERR to a file using ">& nameoffile" under csh or "2> 
nameoffile" under bash) beacause you'll be recording your whole sessions 
instead of just the errors ;)

Now be a good citizen, go to freebsdmall.com, buy the book and subscribe to 
Freebsd starting with version 7.0 ... ;)

Thanks Dru, for your book sits on besides my computer now, and it will not 
move from there for a really long time :)

Hope it helps :)
