PLEASE don't use csh (even tcsh) for scripting something as important as
a CGI script. See:

http://language.perl.com/versus/csh.whynot


for some reasons. Use a Bourne derivative (bash, ksh, sh, zsh, etc...)
for scripting even if you prefer to use tcsh for interactive sessions.

Now...

You can redirect standard output to standard error by:

"1>&2" or more simply ">&2"

e.g. echo "This is an error" >&2

You can redirect standard error to standard output by (the opposite of
the above):

"2>&1"

e.g. ls foo_bar_and_such_things 2>&1

will redirect the error message "ls: foo_bar_and_such_things: No such
file or directory" to standard output rather than standard error.

I assume that for a web page, everything will want to go to standard
output, so the latter construct is what you require (note that that is
impossible to do in csh!).

I hope this helps, and if you require answers to more specific
questions, please post them. :-)

Dave. :-)
