chown in Mac OS X
By: Strauss K Printer Friendly Format
Change file owner and/or group.
Syntax chown [-fhv] [-R [-H | -L | -P]] owner[:group] file ... chown [-fhv] [-R [-H | -L | -P]] :group file ... Options -R Recurse: Change the mode of file hierarchies rooted in the files instead of just the files themselves. -R -H Follow symbolic links on the command line (by default Symbolic links within the tree are not followed.) -R -L All symbolic links are followed. -R -P No symbolic links are followed. (default) -f Do not display a diagnostic message if chmod could not modify the mode for file. -h If the file is a symbolic link, change the mode of the link itself rather than the file that the link points to. -v Verbose, show filenames as the mode is modified*
The owner and group operands are both optional; however, at least one must be specified. If the group operand is specified, it must be preceded by a colon (:) character.
* The -v option is non-standard and its use in scripts is not recommended.
The ownership of a file may only be altered by a super-user for obvious security reasons.
Notes
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.
The -v option is non-standard and its use in scripts is not recommended.
The owner/group may be either a numeric ID or a name. If a user/group name is also a numeric user ID, the operand is used as a user name.
chown exits 0 on success, and >0 if an error occurs.
Examples
Assign Ursula as the owner of "MyFile.txt" file in the Shared
directory.
$ sudo chown Ursula /Users/Shared/MyFile.txt
Assign Ursula as the owner, and staff as the group for everything in the "tmp" folder
$ sudo chown -R Ursula:staff /Users/Shared/tmp/
