coolda has asked for the wisdom of the Perl Monks concerning the following question:

As the title indicates, i have thousands of files. Each file follows the same format for example each file has a format of:

Gene exp1 exp2 exp3 exp4 ... 1 2 3 4 5 6
I want to take out third column only from every file and put it into one file so i can compare them. The code that i'm working on now requires too many codes. Is there any way i can make this work simpler? any insights tips, or advices will be appreciated. I've been working on this for a week, and i still am struggling..
