Thanks Mirni and Chubler.
I got most of it except the following.
substr(s,1,f-1) --> line before the string that needs to be replaced
sprintf("%-*s", t-f+1, v) --> here "s" represents the entire line. t-f+1 lenght of string being replaced, v is the new string to be inserted. But where are we saying the start and end position to the sprintf function for the new string to be inserted. We are just passing the length of the new string wanted.
Here is where i need little more help. I looked at the sprint function man page but is not of much help.
substr(s,t+1) --> line after substring to be replaced.
And also we are not using any concatenate function to join various substrings. But in sql and other Datawarehouse tools we use concatenate function.
Appreciate your help on this.
