Comment: hi
Can any of the awk gurus around show me how to read 2 columns from a file and load them into an associative array. I have to do this from a ksh script.
e.g if i have a file with 2 columns Stock Price
---------------------
IBM 21
INTEL 12 I should be able to get the price using a map(associative array)stock_price like:
price = stock_price[IBM] thnx in advance
