Following is my script :

Code:
#!/bin/bash
export BASEDIR=/home/whoami
FILE=$BASEDIR/login.txt

MyServer=cat $FILE
MyUser="whoami"
MyPassword="password"

expect -c 'spawn ssh '$MyUser'@'$MyServer' ; expect password ; send "'$MyPassword'\n" ; 'sudo  grep -q  "elevator=noop" /etc/grub.conf' '

      if [ $? -eq 0 ] ; then
         echo "$node" >> ./present
      else
         echo "$node" >> ./not-present
      fi
