-On Unix, \fB\-group\fR gets or sets the group name for the file. A group id
-can be given to the command, but it returns a group name. \fB\-owner\fR gets
-or sets the user name of the owner of the file. The command returns the
-owner name, but the numerical id can be passed when setting the
-owner. \fB\-permissions\fR sets or retrieves the octal code that chmod(1)
-uses. This option also provides limited support for setting permissions
-using the symbolic notation used by the Unix chmod(1) command, following the
-form [ugo]?[[+-=][rwxst],[...]]. Multiple permission specifications may be
-given, separated by commas. E.g., \fBu+s,go-rw\fR would set the setuid bit
-for a file's owner as well as remove read and write permission for the file's
-group and other users. A simplified \fBls\fR style string, of the form
-rwxrwxrwx (must be 9 characters), is also supported (example:
-\fBrwxr\-xr\-t\fR is equivalent to 01755). On versions of Unix supporting
-file flags, \fB\-readonly\fR gives the value or sets or clears the readonly
-attribute of the file, i.e. the user immutable flag \fBuchg\fR to chflags(1).
