However in this case we need to match on lines which have 80 character length.
I changed your solution to the one below.
However, I just realized that although the code works, the logic is incorrect. If len(line)==80, add newline, else add "". This in fact is the opposite of what we are trying to achieve!
Further to this point, the matching criteria does not match the 80 character lines we want, and instead matches everything.
How can I modify the logic of my code to correctly match on 80 char lines and achieve the desired result?
Thanks.

Hi RudiC,
Thanks for the explanation. Both of your solutions work well.
I've just updated the sample file, I would like the solution to cater for lines which are meant to be 80 char in length, and do not need to be condensed.
Interestingly enough, the following seems to work, although the logic doesn't make much sense (as explained in my previous post). Perhaps you can shed some light on this?

Hi there,
I have a couple of files I need to merge. I can do a simple merge by concatenating them into one larger file.
But then I need to filter the file to get a desired result.
The output looks like this:

ORDH

Hi folks.
Could somebody help me write a script or command that will look through a file and for every line that doesn't contain a certain value, merge it with the one above?
For example, the file contains:
SCOTLAND|123|ABC|yes
SCOTLAND|456|DEF|yes
SCOTLAND|78
9|GHI|yes

Hi everyone,
I have two files (A and B) and want to combine them to one by always taking 10 rows from file A and subsequently 6 lines from file B. This process shall be repeated 40 times (file A = 400 lines; file B = 240 lines).
Does anybody have an idea how to do that using perl, awk or sed?... (6 Replies)
Thanks it worked for me. I have one more question on top of that. We had few records which were splitted in 2 lines instead of one. Now i identified those lines. The file is too big to open via vi and edit it. How can i do it without opening the file.
Suppose, I want line number 1001 & 1002 to... (2 Replies)
