ah...I was really skipping the scripted version myself... It worked so well, I got confused.

Code:
$ echo "The sky is blue.^JI like to eat.^JI like nice cars.^Jstaying healthy is fun." |while read line
> do
>   i=2
>   while [ $i -gt 0 ]
>   do
>     echo "$line"
>     i=$(( $i - 1 ))
>   done
>   i=$(( $i + 1 ))
> done

I am probably using ksh, How can I double-check for sure?

Code:
env |grep sh

But, as methyl has pointed out, the $ following the # in the first line of the script is your problem...most likely.

Ok it works but not the way I want it. I do not want an incremental count. I want instead line 1 to be copied 5 times, line 2 to be copied twice, line 3 to be copied 4 times, and line 4 to be copied 7 times. How can I achieve that?

I am thinking that maybe I need to specify the row number and tell the script to make "x" number of copies for that specific row. How should I script it?

You'd really want to re-wrap it all into its own loop to achieve this:

Code:
my_list='5 2 4 7' 
typeset -i h=1 
for n in $my_list 
do 
   sed -n ${h}p Edit4 |while read line 
   do 
      i=${n} 
      while [ $i -gt 0 ] 
      do 
         echo "$line" 
         i=$(( $i - 1 )) 
      done 
      i=$(( $i + 1 )) 
   done 
   h=$(( $h + 1 )) 
done

When I use this script, I get the following message:

Can't open Edit4
Can't open Edit4
Can't open Edit4
Can't open Edit4

sorry, Edit4 would be replaced with your input filename.
