PROGRAM:

NAME


fs_copyacl - Copies an ACL from a directory to one or more other directories

SYNOPSIS


fs copyacl -fromdir <source directory (or DFS file)>
-todir <destination directory (or DFS file)>+
[-clear] [-id] [-if] [-help]

fs co -f <source directory (or DFS file)>
-t <destination directory (or DFS file)>+
[-c] [-id] [-if] [-h]

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:

· If an entry on the source ACL does not already exist on the destination ACL, it is
added.

· 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.

· If an entry on the destination ACL has no corresponding entry on the source ACL, it is
removed if the -clear flag is included and is unchanged otherwise. In other words, if
the -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 -fromdir and -todir arguments.

CAUTIONS


Do not copy ACLs between AFS and DFS files or directories. The ACL formats are
incompatible.

OPTIONS


-fromdir <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.

-todir <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, "/afs/.abc.com"). For further discussion of the concept of
read/write and read-only paths through the filespace, see the fs mkmount reference
page.

-clear
Replaces the ACL of each destination directory with the source ACL.

-id Modifies the Initial Container ACL of each DFS directory named by the -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.

-if Modifies the Initial Object ACL of each DFS directory named by the -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.

-help
Prints the online help for this command. All other valid options are ignored.

EXAMPLES


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

PRIVILEGE REQUIRED


To copy an ACL between AFS objects, the issuer must have the "l" (lookup) permission on
the source directory's ACL and the "a" (administer) permission on each destination
directory's ACL. If the -fromdir argument names a file rather than a directory, the issuer
must have both the "l" and "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" (control) permission on each destination directory or
file's ACL.
