It sounds like a permissions problem to me, I assume you are executing the
command as your user login? There are three ways around this: One use the sudo
package to allow your users to run the command with root permissions. Otherwise
you may be able to create a unique group for the file which can be added to your
users other groups using the useradd & groupadd commands (for details type "man
useradd"), to do this you will need to learn about user and group permissions
(other commands you will need are chown and chmod you can also find out about
these using the man or howto commands or check under /usr/doc/HOWTO for further
information). Finally you can "su root" on the command line, you will be then
asked for the root password, you will have to do this every time you want to
execute the command although it will be usefull in the short term.

I bought a book, considering the savings you make on the operating system and of
course the complexity of linux, I found I needed a good reference guide, I also
use all the free documentation I can find, I can't recall the exact
documentation you will need perhaps someone else on the list knows?
