Hi..
I have data file.. and I could able to print using cat and awk
like this
but I want to receive input from user like this
suppose if I give all, it should display all column, and suppose if I give 1,4,5,8,3
it should display only 1st, 4th,5th,8th,3rd column...
How can I do this...
I have one more problem,
I have one script...using for loop for that.. like this
if for loop executed successfully, I want to display
if not I want to display
please go through attached file
