Shell Programming and Scripting

flyingfish,

First, don't hijack another ones thread but start your own thread.
With the solution of cgkmal you get a space between the first and second line, to avoid this you can use this:

Code:

awk '{printf("%s%s",$0,NR%2?"":ORS)}' file

Code:

awk 'ORS = NR%2 ? " " : "\n"' Source.txt

Here we use a conditional operator, the syntax is: expr ? action1 : action2

ORS = assign the value to the recordseparator ORS

NR%2 ? " " : "\n"

Here we look for the remainder of the division of the linenumber by 2 with the modulo operator %, odd lines give a 1 (true) and even lines give a 0 (false).
If the operator gives true (odd lines) the ORS is a space, otherwise the ORS is a newline.

Hope this helps.

Regards

Worked as magic:

Code:
---------
awk 'ORS = NR%2 ? " " : "\n"' Source.txt > Destination.txt
---------

Nice know it worked for you flyingfish,

Hi Franklin52,

Know that your explanation helps A LOT!!. I undersand much better the logic
used to solve the conditional part.


Many thanks for your valauble assistance.

Best regards

maybe you need to replace below with your path, and put script in the same folder with your file Sales.txt

Code:

#! /usr/bin/perl
