Dear Perlmonks,

I have a file (using new line as a delimiter) that is at the moment storing each kind of information twice. Naturally, I would like to get rid of all duplicates. They come in bundles, so I was thinking of just reading out every second line using a loop and storing this in a new file.

My questions:

1. Is there a regular expression for "even number"/"uneven number"?

2. What is the code for "end of file"?

3. Is there a module that could do it (although I prefer to keep things simple)?

Thanks!
