How do you write a awk script program in unix?
That is a difficult question to answer - the question is rather vague on what you intend to do. An awk script is a file containing awk commands that operate on 1 or more data files, based on selectors and actions resulting from that selector. It all depends on what you want to do with the data. The program itself is just a text file that can be created by any editor and then interpreted with the awk command.

What are Nawk scripts?
Nawk is an Awk replacement on *nix operating systems. It is very good at sorting data in columns and search functions. A classic awk command would be: "$awk '/Home/ {print $3}' file > home.txt" this consists of calling the awk interpretor to open the file "file", telling it to search for the word "Home" and when it finds that, print the 3rd column from that line out to a file named home.txt. Awk automatically uses tab (\t) as the field separator ($FS) and you can change this if the input file uses something else besides the tab, e.g. : or ; or & and so on. there are a lot of awk tutorials on the web and most are pretty good.
