NAME
chown - Changes the owner of files or directories SYNOPSIS
chown [-fhR] owner [:group] file... The chown command changes the owner of the specified files or directories to the specified user name or user ID. STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: chown: XCU5.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. OPTIONS
[Tru64 UNIX] Turns off error reporting. [Tru64 UNIX] If file is a symbolic link, chown -h file changes the owner of the symbolic link. The chown file format changes the owner of the file referenced by the symbolic link. Descends recursively through its directory arguments, setting the specified owner. OPERANDS
The pathname of the file for which ownership is to be changed. A user ID and optional group ID to be assigned to file. The owner portion of this operand must be a user name from the user database or a numeric user ID. Either specifies a user ID to be given to each file named by one of the file operands. If a numeric owner operand exists in the user database as a user name, the user ID number associated with that user name will be used as the user ID. If the group portion of this operand is present, it must be a group name from the group database or a numeric group ID. Either spec- ifies a group ID to be given to each file. If a numeric group operand exists in the group database as a group name, the group ID number associated with that group name will be used as the group ID. DESCRIPTION
[Tru64 UNIX] Only a user with superuser authority can use the chown command. The owner argument must be a valid user name or a valid numerical user ID. The optional group argument must be a valid group name or a valid numerical group ID. EXIT STATUS
The following exit values are returned: The chown command executed successfully and all requested changes have been made. An error occurred. EXAMPLES
To change the owner of the file program.c, enter: chown steffan program.c The user access permissions for program.c now apply to steffan. As the owner, steffan can use the chmod command to permit or deny the other users access to program.c. See the chmod command for details. ENVIRONMENT VARIABLES
The following environment variables affect the execution of chown: Provides a default value for the internationalization variables that are unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization vari- ables contain an invalid setting, the utility behaves as if none of the variables had been defined. If set to a non-empty string value, overrides the values of all the other internationalization variables. Determines the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as opposed to multibyte characters in arguments). Determines the locale for the for- mat and contents of diagnostic messages written to standard error. Determines the location of message catalogues for the processing of LC_MESSAGES. FILES
Contains user names and numeric user IDs. SEE ALSO

NAME
chown -- change file owner and group SYNOPSIS
chown [-fhvx] [-R [-H | -L | -P]] owner[:group] file ... chown [-fhvx] [-R [-H | -L | -P]] :group file ... DESCRIPTION
The chown utility changes the user ID and/or the group ID of the specified files. Symbolic links named by arguments are silently left unchanged unless -h is used. The options are as follows: -H If the -R option is specified, symbolic links on the command line are followed. (Symbolic links encountered in the tree traversal are not followed.) -L If the -R option is specified, all symbolic links are followed. -P If the -R option is specified, no symbolic links are followed. This is the default. -R Change the user ID and/or the group ID of the specified directory trees (recursively, including their contents) and files. Beware of unintentionally matching the ``..'' hard link to the parent directory when using wildcards like ``.*''. -f Do not report any failure to change file owner or group, nor modify the exit status to reflect such failures. -h If the file is a symbolic link, change the user ID and/or the group ID of the link itself. -v Cause chown to be verbose, showing files as the owner is modified. If the -v flag is specified more than once, chown will print the filename, followed by the old and new numeric user/group ID. -x File system mount points are not traversed. The -H, -L and -P options are ignored unless the -R option is specified. In addition, these options override each other and the command's actions are determined by the last one specified. 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. EXIT STATUS
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. On previous versions of this system, symbolic links did not have owners. The -v and -x options are non-standard and their use in scripts is not recommended. SEE ALSO
chgrp(1), find(1), chown(2), fts(3), symlink(7) STANDARDS
The chown utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compliant. HISTORY
A chown utility appeared in Version 1 AT&T UNIX. BSD
