cat in multiple ssh commands does not work

Question

This is probably very basic but unfortunately I have no idea how to google it.

Why doesn't the snippet below work as expected? I mean, how can I make cat point to the remote file?

#!/bin/bash

ssh user@remoteaddress << EOF
  mkdir sandpit
  cd sandpit
  echo "foo" > foo.txt
  echo `cat foo.txt` > foo2.txt
EOF

Use it as:

ssh -t -t user@remoteaddress<<'EOF'
mkdir sandpit
cd sandpit
echo "foo" > foo.txt
cat foo.txt > foo2.txt
xargs kill < pid.txt
exit
EOF

Without quotes around starting EOF all words are subject to shell expansion and reverse quotes are expanded in your current shell not on ssh.

Thanks, this works. Well, what I actually want to do is `kill \`cat pid.txt\``. How should I do in this case? – akai Feb 28 '16 at 16:17
