=head1 DESCRIPTION
|
|
|
|
The fs copyacl command copies the access control list (ACL) from a source
|
|
directory to each specified destination directory. The source directory's
|
|
ACL is unchanged, and changes to the destination directory's ACL obey the
|
|
following rules:
|
|
|
|
=over 4
|
|
|
|
=item *
|
|
|
|
If an entry on the source ACL does not already exist on the destination
|
|
ACL, it is added.
|
|
|
|
=item *
|
|
|
|
If an entry exists on both the source and destination ACLs, the
|
|
permissions from the source ACL entry replace the current permissions on
|
|
the destination ACL entry.
|
|
|
|
=item *
|
|
|
|
If an entry on the destination ACL has no corresponding entry on the
|
|
source ACL, it is removed if the B<-clear> flag is included and is
|
|
unchanged otherwise. In other words, if the B<-clear> flag is provided,
|
|
the source ACL completely replaces the destination ACL.
|
|
|
|

|
|
|
|
When using this command to copy ACLs between objects in DFS filespace
|
|
accessed via the AFS/DFS Migration Toolkit Protocol Translator, it is
|
|
possible to specify files, as well as directories, with the B<-fromdir>
|
|
and B<-todir> arguments. For more information on copying ACLs between DFS
|
|
directories and files, refer to the I<IBM AFS/DFS Migration Toolkit
|
|
Administration Guide and Reference>.
|
|
|
|
=head1 CAUTIONS
|
|
|
|
Do not copy ACLs between AFS and DFS files or directories. The ACL formats
|
|
are incompatible.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-fromdir> <I<source directory>>
|
|
|
|
Specifies the source directory from which to copy the ACL. (Specifying an
|
|
AFS file copies its directory's ACL, but specifying a DFS file copies its
|
|
own ACL.) A partial pathname is interpreted relative to the current
|
|
working directory.
|
|
|
|
=item B<-todir> <I<destination directory>>
|
|
|
|
Specifies each directory for which to alter the ACL to match the source
|
|
ACL. (Specifying an AFS file halts the command with an error, but
|
|
specifying a DFS file alters the file's ACL). A partial pathname is
|
|
interpreted relative to the current working directory.
|
|
|
|
Specify the read/write path to each directory (or DFS file), to avoid the
|
|
failure that results from attempting to change a read-only volume. By
|
|
convention, the read/write path is indicated by placing a period before
|
|
the cell name at the pathname's second level (for example,
|
|
C</afs/.abc.com>). For further discussion of the concept of read/write and
|
|
read-only paths through the filespace, see the B<fs mkmount> reference
|
|
page.
|
|
|
|
=item B<-clear>
|
|
|
|
Replaces the ACL of each destination directory with the source ACL.
|
|
|
|
=item B<-id>
|
|
|
|
Modifies the Initial Container ACL of each DFS directory named by the
|
|
B<-todir> argument, rather than the regular Object ACL. This argument is
|
|
supported only when both the source and each destination directory reside
|
|
in DFS and are accessed via the AFS/DFS Migration Toolkit Protocol
|
|
Translator.
|
|
|
|
=item B<-if>
|
|
|
|
Modifies the Initial Object ACL of each DFS directory named by the
|
|
B<-todir> argument, rather than the regular Object ACL. This argument is
|
|
supported only when both the source and each destination directory reside
|
|
in DFS and are accessed via the AFS/DFS Migration Toolkit Protocol
|
|
Translator.
|
|
|
|
=item B<-help>
|
|
|
|
Prints the online help for this command. All other valid options are
|
|
ignored.
|
|
|

|
=head1 EXAMPLES
|
|
|
|
The following example command copies the current working directory's ACL
|
|
to its subdirectory called F<reports>. Note that the source directory's
|
|
ACL is unaffected. Entries on the F<reports> directory's that are not on
|
|
the source ACL of the current directory remain unaffected as well, because
|
|
the B<-clear> flag is not used.

=head1 PRIVILEGE REQUIRED
|
|
|
|
To copy an ACL between AFS objects, the issuer must have the C<l> (lookup)
|
|
permission on the source directory's ACL and the C<a> (administer)
|
|
permission on each destination directory's ACL. If the B<-fromdir>
|
|
argument names a file rather than a directory, the issuer must have both
|
|
the C<l> and C<r> (read) permissions on the ACL of the file's directory.
|
|
|
|
To copy an ACL between DFS objects, the issuer must have the r permission
|
|
on the source directory or file's ACL and the C<c> (control) permission on
|
|
each destination directory or file's ACL.
