Embedding a file into core.img

[Arbiel (gmx)]

Hi

I'm trying to embed a file into core.img. I followed instructions from 
GNU Grub Manual's 5.4 Embedding a configuration file into Grub and tried 
to replicate the example given there with a config file figuring two lines

     search.fs_uuid the_uuid_of_my_partition root
     set prefix=($root)/boot/grub


I used the following commands

#! /bin/bash
cd "${1}"
cat 1> grub/embed.cfg <<EOF
search.fs_uuid 0aceef09-a694-4105-bade-2dca95a09a08 root
set prefix=($root)/boot/grub
EOF
sudo grub-mkimage -c 'grub/embed.cfg' -o 'grub/grub-image' -O i386-pc -d 
'/usr/lib/grub/i386-pc' -C none search_fs_uuid
sudo chmod +x 'grub/grub-image'
sudo grub-install --boot-directory=/media/maisonnette 
--grub-mkimage=grub/grub-image /dev/sdb 2>grub/msg.log

I get the following error message

grub/grub-image: 1: grub/grub-image: Syntax error: word unexpected 
(expecting ")")

Can anybody tell me what's wrong, knowing that my partition 
/media/maisonnette has nothing to do with the 
0aceef09-a694-4105-bade-2dca95a09a08 partition.

Thank you
