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.
If you want to append to a file, use >> instead of >.
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
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 . . .
This is very convenient if you want to document the command _and_
