Rep:
Calling sort from within awk on multiline input
Hello,
I have a file with records that I'm filtering with the awk command
Quote:
awk '/PokerStars/,/\n\n\n/{if(/^Seat/)print; else if (/^$/)print}'
to give output like this:
Quote:
Seat 1 amkolino (13821 in chips)
What I want to do is sort each block of text by the seat number, i.e., the ouput I want should read:
Quote:
Seat 1 amkolino (13821 in chips)
I tried to achieve this by calling the sort command from within awk:
Quote:
awk '/PokerStars/,/\n\n\n/{if(/^Seat/){
However this makes no change to the output. Would anyone know whats going on?

Code:
awk '{ print $0 | "sort -n +2" }' input_file
but usually complicated things get easier in Perl.

Tried your solution linsaurus, and got the following error:
Quote:
sort: open failed: +2: No such file or directory
Any other suggestions?

Just and addition, I managed to alter the above awk command so that it didnt return an error message:
awk 'BEGIN{RS=ORS="\n\n\n"}{print $0 |"sort -k2"}'
Unfortunately, the output looked like this:
Quote:
The idea is that only one block of text is sorted, then it sorts the next block of text and so on.

Hi.
You need to close pipe explicitly:
Code:
$ awk '{s="sort -k2"; print|s; close(s) }' RS="\n\n\n" infile

As an alternative you could also use the seat number as an array argument and output the data.
