Using Office Commands
Caution
Be careful when changing the owner of a
file or folder. If you change the owner
of a file or folder to an owner other
than the current user name or to an
owner corresponding to a login you
cannot enter, you may not be able to
make changes to the file or folder, and
you will no longer be able to use the
Security command to change the owner
selection back to the original.
Read permissjons: You can use this field to determine
if the contents of your files and folders can be
opened, viewed, or copied by others. This command is
useful to prevent unauthorized users from viewing
confidential or sensitive information. The three types
of access for read permissions are:
o Private--Access to the file or folder is
restricted to its owner, typically your user
name, so that only you can open it and see
its contents or make a copy of it. You must
be logged in with the user name shown under
Owner: to view its contents or to copy it.
Note
If a file's read permission is private,
it is also print-protected. Change its
permission to public and print it; then
change its read permission back to
private.
o Public--All users of your UNIX PC system can
open and view the contents of the file or
folder and copy its contents.
o ~--All users of a group you have set up
can open and view the contents of the file or
folder and copy its contents. Groups can be
created only if you have installed certain
applications that support group access.
