unable to read the output to run the next command

When this script is executed I get the PID. Now I want to read the output "PID" and run the next command in this way:

ps -ef | grep -i PID  
ps -ef | grep -i PID  

while read -r -u10 server port line  
do  
  echo ==========  server: "$server" port: "$port"  ==========  
  ssh -qn "$server" "netstat -tulpunt | grep -E ":$port "" | \
      awk '{print $7}' | grep '/' | awk -F "/" '{print $1}'  
  echo  
done 10< demo
