IF condition failing in a SSH script

Hi,

I'm ssh-in to a remote machine (ubuntu) and trying to execute a little script in there.The script looks like this:

Code:

ssh user@ubuntu <<EOF
cd ~/test
ls -l
echo "Continue counting files starting with a`s ?"
read answer
if [ "$answer" = y ]
then 
ls -l a*
else
exit
fi
EOF

Now everything works fine up to the IF test. The script seems to escape the read command, (doesn't prompt ), and all the rest of the IF gets ignored. It shows an error near the "then" part. I tried building a local script in the remote machine and recalling that from the SSH script, but that seems to fail too. Built a simple script with the case condition but that seems to have an error - "unexpected end of file", even though everything looks correct,( checked even with od -c for any hidden character)
In other words every simple script that I built with a test condition in a SSH script
seems to fail.

Anybody any ideas ?

And in general, is there a rule that I should keep in mind when executing a test condition in a remote machine thru a SSH script ?

NAME

     ssh-argv0 -- replaces the old ssh command-name as hostname handling

SYNOPSIS

     hostname | user@hostname [-l login_name] [command]

     hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
     [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]

DESCRIPTION

     ssh-argv0 replaces the old ssh command-name as hostname handling.  If you link to this script with a hostname then executing the link is
     equivalent to having executed ssh with that hostname as an argument.  All other arguments are passed to ssh and will be processed normally.

OPTIONS
