CHOWN(1)            RISC/os Reference Manual             CHOWN(1)



NAME
     chown - change file owner

SYNOPSIS
     chown [-h] [-R] owner file ...

DESCRIPTION
     chown changes the owner of the files to owner.  The owner
     may be either a decimal user ID or a login name found in
     /etc/passwd file.

     If chown is invoked by other than the super-user, the set-
     user-ID bit of the file mode, 04000, is cleared.

     Only the owner of a file (or the super-user) may change the
     owner of that file.

     Valid options to chown are:

     h    If the file is a symbolic link, change the owner of the
          symbolic link.  Without this option, the owner of the
          file referenced by the symbolic link is changed.

     R    Recursive.  chown descends through the directory, and
          any subdirectories, setting the ownership ID as it
          proceeds.  When symbolic links are encountered, they
          are traversed.

     The operating system has a configuration option
     {_POSIX_CHOWN_RESTRICTED}, to restrict ownership changes.
     When this option is in effect the owner of the file is
     prevented from changing the owner ID of the file.  Only the
     super-user can arbitrarily change owner IDs whether this
     option is in effect or not.

FILES
     /etc/passwd

NOTES
     In a Remote File Sharing environment, you may not have the
     permissions that the output of the ls -l command leads you
     to believe.  For more information, see the Mapping Remote
     Users section of the Remote File Sharing chapter of the Sys-
     tem Administrator's Guide.
