This part of awk:
Code:
/Amount/ && /TotalSales/

Does it mean that if one of the pattern is absent, then it will ignore the entire line? I've never heard of using the && for awk. Powerful stuff!

Yes correct.
/Amount/ && /TotalSales/
Means line that have both Amount and TotalSales in it.
Logical and. Look at output of data in my post #6
Logical or can be used this way /Amount/ || /TotalSales/ or /Amount|TotalSales/

@Scrutinizer
Here we could have set RS=R, since capital R is only used in the Record
Code:
awk '/Amount.+TotalSales/{print $3,$5,$7}' RS=R OFS=,

@Jotne, yes we could. Usually that would be too thin a solution, but in this case I guess it could sort of work... If they decided to sell Raspberries that would be regarded as a new record, but since it would not get printed the output would still be OK with this specific input...
