This subcommand returns or sets platform specific values associated
with a file. The first form returns a list of the platform specific
flags and their values. The second form returns the value for the
specific option. The third form sets one or more of the values. The

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 command does also has limited support for setting using the
symbolic attributes for chmod(1), of the form [ugo]?[[+\-=][rwxst],[...]],
where multiple symbolic attributes can be separated by commas (example:
\fBu+s,go\-rw\fR add sticky bit for user, remove read and write
permissions for group and other). 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).
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 retrieves or sets a file's
access permissions, using octal notation by default. This option also
provides limited support for setting permissions using the symbolic
notation accepted by the \fBchmod\fR command, following the form
[\fBugo\fR]?[[\fB+-=\fR][\fBrwxst\fR]\fB,\fR[...]]. 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. An
\fBls\fR-style string of the form \fBrwxrwxrwx\fR is also accepted but
must always be 9 characters long. E.g., \fBrwxr-xr-t\fR is equivalent
to \fB01755\fR. On versions of Unix supporting file flags,
\fB-readonly\fR returns the value of, or sets, or clears the readonly
attribute of a file, i.e., the user immutable flag (\fBuchg\fR) to the
\fBchflags\fR command.

On Windows, \fB\-archive\fR gives the value or sets or clears the
