using expect in bash for multiple independent commands
 
I have a bash script which will run multiple commands against 35-50 remote systems. I cannot use RSA keys (yet). ONE of the jobs of the script is to install my public key on these systems (I have the root passwords for all of them).
The script successfully uses expect with ssh to login and create the .ssh directory, but the expect for the next command, scp, does not run at all. I have turned on exp_internal 1 and I get no output from it. It's as if the expect is ignoring the spawn. (The $cpyparms is properly expanded with lvm being expanded too, before the 2nd expect is started)

Here is the relevant portion of my script:
Code:

#!/bin/bash
cmd1="mkdir ~root/.ssh"
lvm="mydomain"
cpyparms="~/.ssh/rootskey.pub root@"${lvm}":~/.ssh"
      echo "creating sshdir on" $id
VAR=$(/usr/local/bin/expect -c "
spawn ssh $user@$lvm $cmd1
expect \"password:\"
send \"secretpass\r\"
expect \"\r\n\"
expect EOF
")
          echo "#---- copying sshkey from myself ----#"
VAR=$(/usr/local/bin/expect -c"
exp_internal 1;
spawn scp $cpyparms
expect \"password:\"
send \"secretpass\r\"
expect \"\r\n\"
")

Thank you.

Thanks for the tip. I did not understand that the # icon was for adding those tags. I've done it.

")


This problem still exists. If anyone has a clue as to how I can fix it or how I can debug it, I would appreciate the help!
