sed script
Smilie

I have a series of folders /temp/a /temp/b /temp/c

In folders a, b, and c, I have files
a1.txt..........a20.txt
b1.txt..........b40.txt &
c1.txt..........c60.txt

Each file has the same data format :-

Line 1 AAAAA aaaa
Line 2 BBB bbbbbb
Line 3 CCCC cccccc
Etc etc

I need to write a sed script which will go through all the files and reformat the data thus :-

Line 1 AAAAA aaaa
Line 2 BBB
Line 3 X bbbbbb
Line 4 CCCC cccccc
Etc etc

So I need to insert a CR/LF in line 2 position 4,
create a new Line 3 with a constant text (X) and the value of what was to the right of the previous Line 2 (bbbbbb)
and move the remaining lines one line down.

Can anyone help please ?
