[sudo-users] sudo problems with internal shell command

[Stier, Matthew]

If you read the manpage, you can save invoking 'su' unnecessarily.

% sudo -s 'echo disable > /proc/acpi/ibm/bluetooth'

If this is being invoked within a script, you may wish to add the '-n'
option.

No, it is the ">" redirection that runs without the privileges gained
via sudo.
