There is no no need to create the file beforehand. The > redirection
will do one of the following automatically:

	a) file not there ---> file will be created

	b) file there ---> file content will be overwritten

So a command like

	# kldstat -v > /root/kldstat.txt

will work no matter if the output file is already there or not.
This is the shell's default behaviour.

Sidenote:

If you want to append to a file, use >> instead of >.

Sidenote 2:

The easiest way to create an (empty) file is to use the "touch"
program, for example if you want to add the output of several
commands to a file:

	# touch /root/stuff.txt
	# ls / >> /root/stuff.txt
	# kldstat -v >> /root/stuff.txt
	# dmesg >> /root/stuff.txt

Sidenote 3:

In case you want to record a whole terminal session, including
commands and their outputs, use the "script" program:

	# script /root/session.txt
	. . . your commands here . . .
	# exit

This is very convenient if you want to document the command _and_
their outputs.
