What shell do you have?
For that matter, what does your input data look like? Maybe there's a way to do it in pure shell instead of calling awk n times.
Hi Corona688, instead of using the following code to assign variables cs3, cs4, cs5, cs6, cs7, cs8 and cs9, I used the for loop mentioned in the thread. But, the for loop is not working. Please help.
