Command : cd /etc/init.d

3. using vi /gedit editor write a script
    file with extension .sh.
          command  : vi anil.sh

 "WELCOME TO EmbeddedForus "
   

4. For use as script file do the
     following changes .
  

#!/bin/sh
    echo " "
  echo "WELCOME To EmbeddedForus "

  echo " "

5. Save the file
