When you use a directory name as a file name argument, @command{tar} acts on
all the files (including sub-directories) in that directory.
+@node List Extended Attributes
+@unnumberedsubsec Listing xattrs, POSIX ACLs and SELinux context
+
+From upstream GNU tar 1.26.9, tar is able to store, extract and list extended
+file attributes. Listing of those attributes is then active only in verbose and
+double-verbose mode.
+
+This section exercises how to list attributes on examples. Lets start with
+simple verbose mode. This output is inspired by GNU @command{ls -l} command
+output.
+
+@itemize @bullet
+@item
+Show only pure extended attributes.
+
+@smallexample
+$ tar --xattrs --list -v archive.tar
+-rw-rwxr-- user/group 0 2012-08-08 15:15 acls.txt
+-rw-rw-r--* user/group 0 2012-08-08 15:15 xattrs.txt
+@end smallexample
+
+Note the asterisk on the third line! It reflects the situation that the file
+'xattrs.txt' has some extended attribute set. The default mode (same as if you
+are extracting extended attributes) shows information only about extended
+attributes from 'user.*' domain. Anyway, feel free to change the sensitivity
+using @option{--xattrs-include} or @option{--xattrs-exclude} options.
+
+@item Show only POSIX ACLs - the character you should look for is '+':
+
+@smallexample
+$ tar --acls --list -v archive.tar
+-rw-rwxr--+ praiskup/praiskup 0 2012-08-08 15:15 acls.txt
+-rw-rw-r-- praiskup/praiskup 0 2012-08-08 15:15 xattrs.txt
+@end smallexample
+
+@item Show only SELinux - the key character is '.':
+
+@smallexample
+$ tar --selinux --list -v archive.tar
+-rw-rw-r--. praiskup/praiskup 0 2012-08-08 15:16 selinux_only.txt
+-rw-rw-r-- praiskup/praiskup 0 2012-08-08 15:15 xattrs.txt
+@end smallexample
+
+@item
+Show info about ACLs, SELinux and general extended attributes together:
+
+@smallexample
+$ tar --selinux --acls --xattrs --list -v archive.tar
+-rw-rw-r--. praiskup/praiskup 0 2012-08-08 15:16 selinux_only.txt
+-rw-rwxr--+ praiskup/praiskup 0 2012-08-08 15:15 acls.txt
+-rw-rw-r--. praiskup/praiskup 0 2012-08-08 15:15 xattrs.txt
+@end smallexample
+
+In this case, the priority of character is '+' > '.' > '*'. You don't see the
+general extended attributes flag ('*' character) on this example because it is
+hidden by '.' (meaning that the file has SELinux context set).
+
+@end itemize
+
+The example of double verbose mode is here. In this output the single verbose
+characters '.', '+' and '*' are also present after the permission string.
+
+@smallexample
+$ tar --xattrs --selinux --acls -tvvf archive.tar
+-rw-rw-r--. praiskup/praiskup 0 2012-08-08 15:16 selinux_only.txt
+ s: unconfined_u:object_r:user_tmp_t:s0

+ s: unconfined_u:object_r:user_tmp_t:s0
+ x: 12 user.xattr
+ x: 12 user.we_like_tar
+@end smallexample
+
+This mode extends tar's output with additional lines beginning with
+distinguishing characters - 's' for SELinux context, 'a' for POSIX Access
+Control Lists and 'x' for generic extended attributes.
+
+In this format, POSIX ACLs are written in SHORT TEXT FORM as specified in manual
+page @command{man 5 acl}.
+
+Use the @option{--xattrs-include} again if you want to print other than default
+'user.*' extended attributes domain:
+
+@smallexample
+$ tar --xattrs --xattrs-include='*' --acls --selinux -tvvf archive.tar
+-rw-rw-r--. praiskup/praiskup 0 2012-08-08 15:16 selinux_only.txt
+ s: unconfined_u:object_r:user_tmp_t:s0
+ x: 36 security.selinux
+-rw-rwxr--+ praiskup/praiskup 0 2012-08-08 15:15 acls.txt

+ x: 36 security.selinux
+ x: 12 user.xattr
+ x: 12 user.we_like_tar
+@end smallexample
+
+As is in @pxref{Option Summary} section described, tar by default stores all
+extended attributes that are available (not only 'user.*' domain). It means
+that the SELinux context and POSIX ACLs (because they are implemented using the
+generic extended attributes on usual file system) may be stored twice sometimes
+-- firstly in "raw" file system binary format and secondly in more portable way
+-- using appropriate system calls (invoked by @command{tar} options
+@option{--selinux} and @option{--acls}).

+@item --xattrs
+This option causes @command{tar} to store, restore or list the extended file
+attributes (for information about extended attributes see @command{man(5)
+attr}).
+
+Note that all extended attributes are stored "as-is" (in file system binary
+format) and the resulting archive may be not fully portable. See the
+@option{--selinux} and @option{--acls} options when you want to deal with these
+types of extended attributes in a better way.
+
+The @option{--xattrs} option implies the option @option{--format=posix} when
+tar is in @option{--create} operation mode. It is the only one format which
+hase usable headers for storing additional file information like extended
+attributes are.
+
+By default, all extended attributes are stored into the archive. The reason is
+that we want to make the backup process as complete as possible by default. On
+the other hand, during extracting only the 'user.*' domain is extracted by
+default. Anyway, this default behaviour may be easily modified by the
+@option{--xattrs-include} and @option{--xattrs-exclude} options.
+
+When you list an archive in verbose mode
+(@command{tar --xattrs --verbose -tf archive.tar}), tar shows the '*' character
+after the permissions string of concrete file ringht to tell you that at least
+one extended attribute is stored with corresponding file.
+
+Double verbose mode (@command{tar --xattrs -tvvf archive.tar}) prints the
+extended attribute length (in bytes) and its ASCII key (for printed examples
+@pxref{List Extended Attributes}).
+
+@option{--xattrs} option has no equivalent short option.
+
+Warnings which occur during impossible writing of extended attributes to
+a file system may be suppressed using the @option{--warning=no-xattr-write}
+option.
+
+@opindex no-xattrs
+@item --no-xattrs
+This option causes @command{tar} not to store/extract or list the current
+extended attributes. This option does not affect options @option{--no-selinux}
+or @option{--no-acls}.
+
+The @option{--no-xattrs} option has no equivalent short option name.
+
+@opindex xattrs-include
+@opindex xattrs-exclude
+@item --xattrs-include=MASK
+@itemx --xattrs-exclude=MASK
+
+These options allows the xattr store/restore/list process to be more fine
+grained. The default configuration is that @option{--create} mode handles all
+available extended attributes and the @option{--extract}/@option{--list} mode
+handles only 'user.*' domain. These options may be used for editing of this
+default behaviour.
+
+@itemize @bullet
+@item
+Lets say we want to store all attributes except some "public restricted" domain
+(e.g. 'user.restricted.*' domain. The correct way how to do it is:
+
+@command{tar --xattrs --xattrs-include='*' --xattrs-exclude='user.restricted.*'
+-cf archive.tar FILES}
+@item
+And, when we want to extract only some specific domain from an archive - we can
+use:
+
+@command{tar --xattrs --xattrs-include='security.capability' -xf archive.tar
+FILES}
+@end itemize
+
+Multiple passed include/exclude patterns are combined together. The attribute
+is covered then only if (1) at least one of all include patterns matches its
+keyword and (2) no exclude pattern matches its keyword.
+
+When only include pattern is set - exclude pattern is left in default mode (and
+vice versa).
+
+@opindex selinux
+@item --selinux
+This option causes @command{tar} to store/extract/list the SELinux context
+information into/from an archive. Command @command{tar} is able to show info
+whether the SELinux context is present in archived file using the verbose
+listing mode (@command{tar --selinux -tvf archive.tar}). It shows the '.'
+character after permission string in that case. Double-verbose listing mode
+(@command{tar -tvvf archive.tar}) then prints the full SELinux context to
+standard output, @pxref{List Extended Attributes} for printed example.
+
+This option implies the @option{--format=posix} when @command{tar} works in
+@option{--create} operation mode.
+
+Warnings complaining that SELinux context may not be written to a file system
+may be suppressed by the @option{--warning=no-xattr-write} option.
+
+The @option{--selinux} option has no equivalent short option name.
+
+@opindex no-selinux
+@item --no-selinux
+This option causes @command{tar} not to store the current SELinux security
+context information in the archive and not to extract any SELinux information in
+an archive.
+
+The @option{--no-selinux} option has no equivalent short option name.
+
+@opindex acls
+@item --acls
+This option causes @command{tar} to store the current POSIX access control lists
+into the archive or restore POSIX ACLs from an archive. It also allows
+@command{tar} to show whether archived file contains ACLs when the verbose mode
+is active (@option{tar --acls -tvf} shows the symbol '+' after the permission
+characters in that case). Double-verbose mode allows @command{tar} to list
+contained POSIX ACLs (@command{tar --acls -tvvf archive.tar}), for printed
+examples @pxref{List Extended Attributes}.
+
+This option implies the @option{--format=posix} when @command{tar} works in
+@option{--create} operation mode.
+
+Warnings complaining that POSIX ACLs may not be written to a file system may be
