You may want to read up on 'for' and 'while' loops. What language is this in?

Code:
while read line
 do 
   for i in 1 2 3 4 5
     do 
      echo $line
     done
 done < file

or in awk:

Code:
awk '{for(i=1;i<=5;i++) print }' file

Neither of those solutions would work, because he is iterating by two values - X and Y. He needs to use a nested for statement, which is why I asked what language this is.

Either way, I have a funny feeling this is a homework assignment... Call me naive...

On the contrary, both solutions would work since the stated aim is to repeat each line five times.

Here's my effort...
Code:
paste -d '\n' $(yes file1|head -5)

...or...
Code:
sed 'p;p;p;p' file1

And mine:

Code:
perl -pe'$_=$_ x5' file

Code:
ruby -pe'4.times{print}' file

Code:
awk '{while(++i<6)print;i=0}' file
