top-level directory to the archive, but not its contents.

|
|
|
+Starting with this version tar is able to store, extract and list
|
|
|
|
|
+extended file attributes, POSIX.1e ACLs and SELinux context. This is
|
|
|
|
|
+controlled by the command line options --xattrs, --acls and --selinux,
|
|
|
|
|
+correspondingly. Each of these options has a `--no-' counterpart
|
|
|
|
|
+(e.g. --no-xattrs), which disables the corresponding feature.
|
|
|
|
|
+Additionally, the options --xattrs-include and --xattrs-exclude allow
|
|
|
|
|
+you to selectively control for which files to store (or extract) the
|
|
|
|
|
+extended attributes.
