Ugly answer, but should work and not waste time

This might be an ugly solution but you could write a little loop, im not exactly sure of the syntax, Ill look it up if you want. (It's on google) But any way that does:


#!/bin/bash
donevar=0

wget http://somesite/file.tar &

while [donevar=0]; do
if [ -s "file.tar" ]; then
tar xvf file.tar
donevar=1
else
#you can pause if you want it doesn't really matter
fi
done



if you want you could get rid of the if, but I think it is uglier:

#!/bin/bash

wget http://somesite/file.tar &

while [! -s file.tar]; do
#you can pause if you want it doesn't really matter
done

tar xvf file.tar

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

NAME
virt-tar-out - Pack a virtual machine disk image directory into a tarball. SYNOPSIS
virt-tar-out -a disk.img /dir files.tar virt-tar-out -d domain /dir files.tar virt-tar-out -d domain /dir - | gzip --best > files.tar.gz DESCRIPTION
"virt-tar-out" packs a virtual machine disk image directory into a tarball. The first parameter is the absolute path of the virtual machine directory. The second parameter is the tar file to write. Use "-" to write to standard output. EXAMPLES
Download the home directories from a guest: virt-tar-out -d MyGuest /home - | gzip --best > homes.tar.gz JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH
This command is just a simple shell script wrapper around the guestfish(1) "tar-out" 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
