Edit a text file with perl

[ironmonkey69]

Can anyone help me write a perl script that edits a text file? The test file has three line of text and twelve columns of numbers. The ranges of numbers are 0-2500. the first number in all of the columns is zero. I need to be able to select one of the colums and be able to change all the values in that column to zero.

NO.

What have you tried thus far?

I have tried using different regular expressions to select a colum but have only been able to select the last column and zero that one out.

Show us the code.

I have a feeling that the following will most likely become helpful:

All your code, including that to process the text file. And while you're at it, the test file itself.
