For menus i recommend case with while true
Use trap, log shell function and break for complete control of user input (readers curiosity)
Code:
while true
do
clear
## display part
printf "This is a menu
a) run command a
b) run command b
\n"
read ANSWER
case $ANSWER in
## Execution part
a) tar cf home.tar /home/user ## or whatever you wish to execute.
;;
b) tar xf home.tar /home/user
;;
*) printf "fail \n" ; sleep 1
;;
esac
done

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.
