Indeed, you have an open-ended single-quote which should be closed.

But...you have bigger problems than that, because this is a *remote* script. So, statements like this:

Code:
ssh HOST <<EOF
    echo $HOSTNAME
EOF

will show the local value of HOSTNAME, since the script is evaluated by the shell before it is sent to the remote host. So, all variables that you don't want evaluated need to be escaped (i.e., "\$HOSTNAME"). If you don't need to reference ANY local variables, you can prevent the script from being evaluated be escaping the "EOF" separator:

Code:
ssh HOST <<\EOF
    # the backslash above will prevent the Variables below from being evaluated
    echo $HOSTNAME
EOF

Generally, when attempting to code/debug these kinds of scripts, you should send them to a local file to ensure the code evaluates the way you expect, and then you can run "sh -n" to verify the syntax:

Code:
cat <<EOF > /tmp/test.script
    # this is a temporary location
    echo $VALUE1 \$VALUE1
EOF

SSH-COPY-ID(1)						      General Commands Manual						    SSH-COPY-ID(1)

NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine and append the indicated identity file to that machine's ~/.ssh/autho- rized_keys file. If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your ssh-agent. Otherwise, if this: ssh-add -L provides any output, it uses that in preference to the identity file. If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin- gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory, if necessary.) NOTES
This program does not modify the permissions of any pre-existing files or directories. Therefore, if the remote sshd has StrictModes set in its configuration, then the user's home, ~/.ssh folder, and ~/.ssh/authorized_keys file may need to have group writability disabled manu- ally, e.g. via chmod go-w ~ ~/.ssh ~/.ssh/authorized_keys on the remote machine.
