I know this is probably super simple, but I am very new to Perl, and programming (I am learning via tutorials now). I can't seem to find how to do the following (and yes, I have been googling all over for the answer):

My current hosts file format:

1.1.1.1   01computer12   01computer12.abc.com
1.1.1.2   34computer21   34computer21.abc.com

[download]
etc etc
I need to append another alias at the end of each line based on the content of the line - so it's not a simple search and replace - and it would look like this: 
1.1.1.1   01computer12   01computer12.abc.com  01host12
1.1.1.2   34computer21   34computer21.abc.com  34host21

[download]
and so on. Do I read the second column into a variable, edit that variable, then append it to the end of the line? I'm just unsure how to proceed. I'm not asking for anyone to write it for me, I could just use some ideas/direction, or any kind of help you can offer.

Thanks!!!!
