Hi,

You can use the below script.

Code:
y=1
while read line
do
fld1=`echo $line |cut -d' ' -f1|tr -d ' '`
if [ "$fld1" = 'Data' ]; then
   fld2=`echo $line|cut -d'"' -f2|cut -d'#' -f1|tr -d ' '`
   fld3=`expr $fld2 + 1000000`
   sed -i "$y s/$fld2/$fld3/" test1
elif [ "$fld1" = 'ID' ]; then
   fld2=`echo $line|cut -d' ' -f2|tr -d ' '`
   fld3=`expr $fld2 + 1000000`
   sed -i "$y s/$fld2/$fld3/" test1
fi
y=`expr $y + 1`
done < inputfile
exit 0

Code:
Input file :
 
Data "12345#22"
Fred
ID 12345
Age 45
Wilma
Dino
Data "123#22"
Tarzan
ID 123
Age 33
Jane

Code:
Output file : 
 
Data "1012345#22" 
Fred 
ID 1012345 
Age 45 
Wilma 
Dino 
Data "1000123#22" 
Tarzan 
ID 1000123 
Age 33 
Jane

If the final number has to be < 2000000 then you will need to put a check before using 'sed' so that the original value is not updated.

Regards,
RM
