grep -w 'pvvd_inst' $rvst_clas_name >> tempfile1
        
    if  [ `ll inst_fncn.tmp | awk {'print$5'}` -eq 0 ] ;
        then
  Now I am checking the filesize , If its equal to zero thn i am concluding 
  inst fncn not callled in this class
  echo ""
  echo "pvvd_inst not called in this class "$rvst_clas_name""

   The problem starts with else part .... How do i proceedc  
        
 else
 In the else part , The logic that i developed is to  read the file line by line
 Capture text between opening and closing braces of each function .. and then grep 
 but I am running short of how to implement these ideas ...
