Hi getmmg,

Can you please use the input file below. So instead of letter you will use numbers.

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.

Hi getmmg,

What do you think its giving me a wrong output...?

Code:
root@pinpe>perl -0ane 'BEGIN{$cols=3;$k=0}END{$total=($#F+1)/$cols;foreach(@F){$hash{$k}.= "$_\t";$k++; $k=0 if($k == $total)}; print "$_\n" for values %hash}' test.txt 
51      18      7025    
57      527     1807367 
29      87868   730     
389     382     5       
4       10625   8614

Thanks,
Pete

Code:
gawk -v row=3 '{arr[NR%row]=arr[NR%row]" "$0} END{n=asort(arr);for(i=1;i<=n;i++){print arr[i]}} ' test.txt

Try this one with gawk/nawk, this should work

Hello Pinpe,

I guess it's giving the output properly ( order is missing ) . Check it out how to get the output in the order you read!!!

Regards
Ravi

389     382     5       
4       10625   8614


I was getting the output in exact order. In that case add the sort like below and try
Code:
 
 
print "$hash{$_}\n" for sort keys %hash}' test


Thanks,
Pete

Hi kumaran_5555,

My OS is Sun Solaris Unix based. Can you convert your code to Unix please... It is giving me an error...

Code:
root@pinpe>nawk -v row=3 '{arr[NR%row]=arr[NR%row]" "$0} END{n=asort(arr);for(i=1;i<=n;i++){print arr[i]}} ' test.txt
nawk: calling undefined function asort
 input record number 81, file test.txt
 source line number 1
root@pinpe>gawk -v row=3 '{arr[NR%row]=arr[NR%row]" "$0} END{n=asort(arr);for(i=1;i<=n;i++){print arr[i]}} ' test.txt

CORRECT>awk -v row=3 '{arr[NR%row]=arr[NR%row]" "$0} END{n=asort(arr);for(i=1;i<=n;i++){print arr[i]}} ' test.txt (y|n|e|a)?

Thanks in advance.
