First time poster here and I'm pretty much a total noob with UNIX and Perl. So please bear with me.
With Perl, I'm trying to fill an array with data that is in a CSV file. I would like to fill the array with only one of the columns in the CSV file.
I have a file called data.csv:
What I would to have is an array that contains only one of the columns: i.e.
As far as code goes, as far as I can get is to print every line in the file:
I believe that I have to use the split() function, but i'm not sure how.
Also, I have seen lines of code that look like Tie::Hash... But I don't know what its used for.
Thanks in advance
