chown:  Change the ownership of files or directories

Usage:  chown [-ADPrRtTh-] userid file1 [ file2 ... ]

   chown will change the ownership of NTFS files or directories
   to the specified user.  chown will not run under Windows 95.

   The userid may be specified as either a simple name or as a
   machine\name pair.  (Warning:  specifying a name on another
   machine can take several seconds for network handshaking.)

   To use this command to take ownership for yourself, you must
   have this right:

      Take ownership of files or other objects

   If you would like to grant ownership to another userid, you
   must also have this right:

      Restore files and directories

   These rights can be granted via the User Manager.

Options:

   -A             Add an access control entry to any access
                  control lists, granting full access to the
                  new owner.
   -D             Default ACL.  (Allows full access to the owner,
                  Administators and the System and read/write
                  access to Everyone.)
   -P             Private.  Add an ACL to each file allowing
                  full access to the new owner but no access
                  to anyone else.
   -r             Recursive.  If any of the paths specified
                  is a directory, chown will recursively walk
                  through the entire directory tree, changing
                  the ownership of all the contents.
   -R             Remove any ACL.  (Warning:  a null ACL grants
                  full access to everyone and cannot be edited
                  with the Microsoft cacls command.)
   -t             Take.  Change the ownership to the same as
                  that of the current process.  If you are a
                  member of the Administrators group, ownership
                  will be taken in the name of that group.
                  (This is so that Administrators can easily
                  share files.)  The userid argument is omitted.
   -T             Take ownership in your own name, even if you
                  are a member of the Administrators group.  The
                  userid argument is omitted.

   -h             Help.  (This screen.)
