or for the second one you could do something like

Code:
perl -e ' while (<>) { $a = " " x 20; $_ =~ s/$/$a/; print "$_"  } ' filename

Code:
echo "aaa bbb" | awk '{ printf $1 
                       for (i=0; i<50; i++)   printf " " 
                       print $2
                     } '

If you need the data plus spaces to equal 50 characters:
Code:
printf "%-49s " "data 1" "data 2" "data 3" ...
printf "\n"

If you need 50 spaces between items:
Code:
printf "%s%50%" "data 1" " " "data 2" " " "data 3" " " ...
printf "\n"
