Data Grep and display
I have the following data:

A
1
2
3
A
4
5
6
A
7
8
9

I want to grep this data with A and 3 lines below it then display them in this format:
A 1 2 3
A 4 5 6
A 7 8 9

My grep comand is:

grep +3 "A" datafile

Can someone help me to have the data lay out as describe above?

Many thanks!

I am not sure that you understand the grep command because it seems as though you are trying to format data which is in a fixed order, rather than search for specific patterns of text - which is the main function of grep.

Please confirm this before I continue with some possibilities that may apply?
