Your description is a little confusing. Do you need to alter the second word, the second line, or the second word on the second line?
In any case, you can do this very simply with a Perl one-liner using the $. variable (which is the current line number) and a regular expression. Please post sample input and sample output from that input if you'd like me to give you the one-liner. That is, if you're open to a Perl solution.
