chown(1) (Essential Utilities) chown(1)
NAME
chown - change file owner
SYNOPSIS
chown [-R] [-h] 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:
-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.
-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.
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.

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 System
Administrator's Guide.
