syntax error in commands

syntax error in commands

I have an iframe to send the commands from control panel when the user
clicks the button. Using the code below, nothing happens with the button
when the user clicks as there is a syntax error in the code.
$items['googledotcom'] = array
(
'description'=>'DNS resolution test',
'1'=>1,
'0'=>0,
'fixCommand'=>'EXC service network restart; echo "nameserver
8.8.8.8" >> /etc/resolv.conf; sleep 10; curo health check',
);
The above code doesn't work, because of this line: echo "nameserver
8.8.8.8" >> /etc/resolv.conf;
But the code will work when I remove the above line. But I need to add the
above line as well.
Any suggestions for the syntax?
Thanks!
