Access Control Lists - JFS File Systems Only
Users can permit or deny specific individuals and groups to access a file by setting optional ACL entries
in the file’s access control list (see aclv (5)). When using
chown in conjunction with JFS ACLs, if the new
owner and/or group of a file have optional ACL entries corresponding to
user:uid:perm and/or
group:gid:perm in the file’s access control list, those entries remain in the ACL but no longer have any
effect, being superseded by the file’s
user::perm and/or group::perm entries.
Options
chown and chgrp recognize the following options:
-h Change the owner or group of a symbolic link.
By default, the owner or group of the target file that a symbolic link points to is changed.
With
-h, the target file that the symbolic link points to is not affected. If the target file is
a directory, and you specify -h and
-R, recursion does not take place.
-R Recursively change the owner or group. For each file operand that names a directory, the
owner or group of the directory and all files and subdirectories in the file hierarchy below
it are changed.
EXTERNAL INFLUENCES
Environment Variables
LC_MESSAGES determines the language in which messages are displayed.
If
LC_MESSAGES is not specified in the environment or is set to the empty string, the value of
LANG is
used as a default for each unspecified or empty variable. If
LANG is not specified or is set to the empty
string, a default of "C" (see lang (5)) is used instead of LANG.
If any internationalization variable contains an invalid setting,
chown behaves as if all internationaliza-
tion variables are set to "C". See environ (5).
International Code Set Support
Single- and multi-byte character code sets are supported.
RETURN VALUE
chown and chgrp return the following values:
0 Successful completion.
>0 An error condition occurred.
EXAMPLES
The following command changes the owner of the file
jokes to sandi:
chown sandi jokes
The following command searches the directory design_notes and changes each file in that directory to
owner mark and group users:
chown -R mark:users design_notes
WARNINGS
The default operation of chown and chgrp for symbolic links has changed as of HP-UX release 10.0.
Use the -h option to get the former default operation.
