Hello Respected Monks, I first want to beg your pardon, and let you know that I am a newbie at Perl. I am have been exposed to Perl for about 2 weeks, hence the following question. Let's assume that I have a delimited file as shown:

ABC 123 HELLO

23222 PERL MATLAB

BARCELONA ISTANBUL CAIRO

I want to add a new line to this file with the word data, but I also want the original first line to be the second line, second to be the third, third to be.....ect, and thus, the final processed file should be like this:

data

ABC 123 HELLO

23222 PERL MATLAB

BARCELONA ISTANBUL CAIRO

You get the point, right? Any help you can provide will come back at you as karma points, so please help this poor newbie out on a nice Friday morning.
