Hope this code will your issue.

Code:
perl -0ane 'BEGIN{$cols=3;$k=0}END{foreach(@F){$j=sprintf("%03d",++$k);$hash{$j}.= "$_\t";$k=0 if($k == (($#F+1)/$cols))}; print "$hash{$_}\n" for sort keys %hash}' input

Cheers.

Hi getmmg,

This is one works totally for me. Thank you so much mate!

Now for the final touch, after the desired output into 3 columns I want it to trim the trailing spaces from the output file. Please insert some more code on this perl script.

Thanks again in advance.
