How to Escape Character when Running SSH Remote Command

Solution of Escaping Character on SSH

The solution is DO NOT escape it. Use cat HEREDOC to build the string of commands and then pass it to SSH.

$ export VARIABLE="FOO BAR"
$ cat <<EOF | ssh user@myserver bash
echo "This is complex command"
echo "Another command that take a $VARIABLE."
sudo mkdir /tmp/foo && echo "SUCCESS"
EOF

If you have a lot of $ dollar signs in your script and do not want local shell to interpret it then use single quote HEREDOC.

$ export VARIABLE_NAME="FOO BAR"
$ cat <<'EOF' | ssh user@myserver bash
export VARIABLE="SSH VAR"
echo "This is complex command"
echo "Another command that take a $VARIABLE name."
sudo mkdir /tmp/foo && echo "SUCCESS"
EOF

On command above the variable $VARIABLE value is "SSH VAR" since it is took the value from remote server not from local machine.
