using a vaiable parameters and values to find and tar
This one took HOURS and HOURS of my life. Hopefully this post will save someone the same grief.

I am using "-regex" with "find" via a variable. If I echo the command that is constructed, it looks OK. When I paste the echoed text it to the command line it runs fine. But inside the script it generates an error. This led me to the work around which was to pipe the echoed text to bash.

here is the snippet from the script that matters (using GNU bash, version 3.2.33(1)-release (x86_64-redhat-linux-gnu) - Fedora 8):

echo find "$FOLDER" -type f $EXCLUDE
find "$FOLDER" -type f $EXCLUDE
echo find "$FOLDER" -type f $EXCLUDE | bash

here is the output from above 3 lines:

find etc -type f -not \( -regex '^etc/X11/.*' -o -regex '^etc/fonts/.*' \)
find: paths must precede expression
Usage: find [-H] [-L] [-P] [path...] [expression]
etc/bla
etc/foo

My question is why does the command not work in the script when it works fine on the command line or when piped to bash?

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.
