how does awk ensures the array's index order. Usually it has arbitrary order, an you may end up with different line order in the output.

Hi getmmg,

Still does not work for my desired output. Let me clear my input and outful files as shown below...

inputfile.txt:
Code:
AAA
BBB
CCC
DDD
EEE
FFF
GGG
HHH
III
JJJ
KKK
LLL
MMM
NNN
OOO




output.txt file is like this...
Code:
AAA     FFF     KKK
BBB     GGG     LLL
CCC     HHH     MMM
DDD     III     NNN
EEE     JJJ     OOO

Thanks in advance.

Have you tried my command,

it worked fine.
Code:
cgi@tioman> (/home/cgi) $ awk -v row=5 '{arr[NR%row]=arr[NR%row]" "$0} END{n=asort(arr);for(i=1;i<=n;i++){print arr[i]}} ' test.txt
 AAA FFF KKK
 BBB GGG LLL
 CCC HHH MMM
 DDD III NNN
 EEE JJJ OOO

Hi kumaran_5555,

I'm getting error...

Code:
root@pinpe>awk -v row=5 '{arr[NR%row]=arr[NR%row]" "$0} END{n=asort(arr);for(i=1;i<=n;i++){print arr[i]}}' inputfile.txt
awk: syntax error near line 1
awk: bailing out near line 1

Thanks.

Br,

Hi Pinpe,

if you are using solaris...please use nawk instead of awk as Kumaran has mentioned he tried in Linux.

Thanks

Hi getmmg,

This one works for me but it somehow re-arranged the position of the values. My inputfile is actually a list of numbers and not letters. Can you please modify a little this code of yours? Thanks.

Code:
389    
57     
4      
29     
51     
382    
527    
10625  
87868  
18     
5      
1807367
8614   
730    
7025

The output should be like this...

Code:
389     382       5      
57      527       1807367
4       10625     8614   
29      87868     730    
51      18        7025

Thanks in advance.

Pinpe,

This should work

Code:
 
 
perl -0ane 'BEGIN{$cols=5;$k=0}END{$total=($#F+1)/$cols;foreach(@F){$hash{$k}.= "$_\t";$k++; $k=0 if($k == $total)}; print "$_\n" for values %hash}' inp


I've got following output when the cols was given as 5 and then as 3.
Let me know if this is what you require.

Output I got

Code:
 
 
5 cols
 
AAA DDD GGG JJJ MMM
BBB EEE HHH KKK NNN
CCC FFF III LLL OOO
 
3 cols
 
AAA FFF KKK
BBB GGG LLL
CCC HHH MMM
DDD III NNN
EEE JJJ OOO
