CHOWN(8)                386BSD System Manager's Manual                CHOWN(8)

NAME
     chown - change file owner and group

SYNOPSIS
     chown [-Rf] owner [:group] file ...
     chown [-Rf] :group file ...

DESCRIPTION
     Chown sets the user ID and/or the group ID of the specified files.

     The options are as follows:

     -R      Change the user ID and/or the group ID for the file hierarchies
             rooted in the files instead of just the files themselves.

     -f      Don't report any failure to change file owner or group, nor
             modify the exit status to reflect such failures.

     The owner and group operands are both optional, however, one must be
     specified.  If the group operand is specified, it must be preceded by a
     colon (``:'') character.

     The owner may be either a numeric user ID or a user name.  If a user name
     is also a numeric user ID, the operand is used as a user name.  The group
     may be either a numeric group ID or a group name.  If a group name is
     also a numeric group ID, the operand is used as a group name.

     The ownership of a file may only be altered by a super-user for obvious
     security reasons.

     The owner and group of symbolic links are themselves changed instead of
     the file to which the link points.

     The chown utility exits 0 on success, and >0 if an error occurs.

COMPATIBILITY
     Previous versions of the chown utility used the dot (``.'') character to
     distinguish the group name.  This has been changed to be a colon (``:'')
     character so that user and group names may contain the dot character.

SEE ALSO
     chgrp(1),  find(1),  chown(2)

STANDARDS
     The chown command is expected to be POSIX 1003.2 compliant.
