Code:

set -A array $(</tmp/inputfile) #reading file in array

c= ${#array[*]} #the no. of elements in the array
 
i=1
 
while [ $i -lt $c ]
do
   j=`expr $i +1`
   v1=`echo ${array[$i]}|cut -d" " -f1`
   v2=`echo ${array[$j]}|cut -d" " -f1`
   
   if [ $v1 = $v2 ]
       then
             array[$i]=`echo F.${array[$i]}`
   fi
   i=`expr $i +1`
done
 
i=1
 
while [ $i -le $c ]
do
   x=`echo ${array[$i]|cut -c1`
   
   if [ $x -ne "F" ]
     then
           `echo ${array[$i]}>>newfile`
   fi
done
 
`cat newfile`

see if the code given above works.

here i am trying to store each lines of the inputfile in an array.
c is the number of array elements. (or the numbert of lines in the input file.)
i am checkimg of the two consecutive fileds have same value. if true i am setting F as the 1st character in the 1st of the two lines. then store the same in the array.

later in another loop i am checking if the 1st character of any line is not F (this marks that this line has not been repeated). if true i am writing that to newfile.

newfile is the reqd ouput file.
