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:

To read a compressed file without having to first uncompress it, use
"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 :)
