Maybe something like:

This is the output for tar xvf a.tar
Code:
# tar xvf a.tar
x RET20120101.dat.Z, 939194 bytes, 1835 media blocks.
x RET20120102.dat.Z, 939194 bytes, 1835 media blocks.

If I do below, there is no ouput.
Code:
tar xvf a.tar | grep '.Z$'

If I do below, it's almost there but the extra , after the .Z is causing problem. Any suggestion how to get it right?
Code:
# tar xvf a.tar | grep '.Z'  | xargs gzip -d -S ""
x: No such file or directory
RET20120101.dat.Z,: No such file or directory
939194: No such file or directory
bytes,: No such file or directory
1835: No such file or directory
media: No such file or directory
blocks.: No such file or directory
x: No such file or directory
RET20120102.dat.Z,: No such file or directory
939194: No such file or directory
bytes,: No such file or directory
1835: No such file or directory
media: No such file or directory
blocks.: No such file or directory

virt-tar-in

virt-tar-in(1)						      Virtualization Support						    virt-tar-in(1)

NAME

       virt-tar-in - Unpack a tarball into a virtual machine disk image.

SYNOPSIS

	virt-tar-in -a disk.img data.tar /destination

	virt-tar-in -d domain data.tar /destination

	zcat data.tar.gz | virt-tar-in -d domain - /destination

WARNING

       Using "virt-tar-in" on live virtual machines can be dangerous, potentially causing disk corruption.  The virtual machine must be shut down
       before you use this command.

DESCRIPTION

       "virt-tar-in" unpacks an uncompressed tarball into a virtual machine disk image or named libvirt domain.

       The first parameter is the tar file.  Use "-" to read the tar file from standard input.	The second parameter is the absolute target
       directory to unpack into.

EXAMPLES

       Upload a home directory to a guest:

	virt-tar-in -d MyGuest homes.tar /home

JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH

       This command is just a simple shell script wrapper around the guestfish(1) "tar-in" command.  For anything more complex than a trivial
       copy, you are probably better off using guestfish directly.

OPTIONS

       Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options.

SEE ALSO

       guestfish(1), virt-cat(1), virt-copy-in(1), virt-copy-out(1), virt-edit(1), virt-make-fs(1), virt-tar-out(1), <http://libguestfs.org/>.
