using ruby, i am trying to read a file of a couple hundred lines into an 
array and prepend (if there is such a word) the line number (starting at 1)  
to the beginning of each line.  

a simple example from the file follows :
01/02/2004 bought 100 widgets 19.95 company_1
01/02/2004 sold 5 widgets 22.95 company_2
01/02/2004 bought 50 widgets 19.95 company_1

what i would like to end up with is :

1 01/02/2004 bought 100 widgets 19.95 company_1
2 01/02/2004 sold 5 widgets 22.95 company_2
3 01/02/2004 bought 50 widgets 19.95 company_1


is there an array method that i can use on each element to prepend the line 
number after reading the file into an array using IO.readlines?  

thanks

joe
