Top Forums UNIX for Beginners Questions & Answers Issues with sorting in reverse order Post 302986872 by rbatte1 on Thursday 1st of December 2016 05:43:33 AM

I'm stumped on the point of sorting the file at the end. The first line you write to identify the file will be very unlikely to stay with the content, and the content itself may not stay in order either.

What are you trying to achieve? There is probably a far neater way to achieve it as Don alludes to, but we would need to know what inputs/files you have and what is the required output.


For instance:-
Quote:
I have three directories (for testing) dir-a, dirb and dir-c
They all contain separate files file-a, file-b & file-c respectively
Each file contains my data.

The output I want is:-
Code:
dir-c/file-c:
Data-c line1
Data-c line2
Data-c line3
dir-b/file-b:
Data-b line1
Data-b line2
Data-b line3
dir-a/file-a:
Data-a line1
Data-a line2
Data-a line3

You would be best to tell us which bits need to be sorted (reverse) and which bits need to remain as they are.


I'm sure we can help if we fully understand the problem.


Kind regards,
Robin
