Hello,
Our group is just starting to get into UNIX here. We are former REXX users on a VM Mainframe. Can someone point me to the documentation to read a file and write a file in a Unix Shell Script or does this have to be done in another language?
Thank you in advance...

virt-copy-out
virt-copy-out(1) Virtualization Support virt-copy-out(1)NAME
virt-copy-out - Copy files and directories out of a virtual machine disk image.
SYNOPSIS
virt-copy-out -a disk.img /file|dir [/file|dir ...] localdir
virt-copy-out -d domain /file|dir [/file|dir ...] localdir
DESCRIPTION
"virt-copy-out" copies files and directories out of a virtual machine disk image or named libvirt domain.
You can give one of more filenames and directories on the command line. Directories are copied out recursively.
EXAMPLES
Download the home directories from a virtual machine:
mkdir homes
virt-copy-out -d MyGuest /home homes
JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH
This command is just a simple shell script wrapper around the guestfish(1) "copy-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.
