One of my colleagues asked this query to me. And I liked the query very much.
So I started thinking about that.
For example i have a below file:
Now i want to find strings in the file , lets say in the order name1, name2, name3, name4.
And i also want the output to be in the same order in the way i searched as below:
Obviously we cannot do this with a single grep command without any temporary files being created.
So I thought perl would be a better option for this. So I came up with a simple perl solution.

And this worked like a a charm.
