Full Discussion: Mix two files line by line

Consider this logic:-
  • You want to read a file called colours
  • For each line it contains, you want to do the following
    • You want to read a file called fruits
    • For each line, you want to display the current colour followed by the current fruit

If you are in a shell script (ksh, bash, etc.) you need to have a loop to read in each file similar to this:-
Code:
while read variable
do
   some action
done < file

Other coding options will exist for awk, sed, perl, csh and the list goes on. This is why it would be good to know what you are starting with this issue. What are you experienced in? That's normally a good way to think about things.

Is this homework perhaps? If so, there is a homework forum.


Does that help? Would you like to experiment and let us know how you get on?
