in thread Check for an empty file

I had some trouble with this a while back. -s returns a zero if the file is either zero bytes or nonexistent. It got a bit confusing until I worked out what was happening.

    Actually, it returns undef (and sets $!) if the file is non-existent.

[hippo]: Yary: There are a few useful pointers in I need perl coding standards
[hippo]: ... and a boatload of good stuff in On Coding Standards and Code Reviews
[Yary]: Looking at system pm's, looks like it's "package" on the first line, then POD, then "use 5.xyz;use strict; use warnings; use modules..."
[Yary]: ah thanks for those links
[hippo]: Just bear in mind that all such ideas are subjective.
[choroba]: There might be a different standard at the shop you write the code for.
[choroba]: The order of package - (strict+warnings | warnings+strict) - modules makes sense, POD and strict-warnings order are not so important
