Re: How can I check from wich OS the script is running?

The $^O that others have described will get you started, and for your *nix uses will be just fine. However it will only say "Win32" for any Windows OS. To require Win NT/2K/XP you can check for the value of $ENV{OS} and make sure it is "Windows_NT". It will be empty (non-existant) for the Win9x OS's. If you want more granularity than that for Windows, you need to start grubbing through the registry.

Note: I'm not sure how the Config solution above will work on something like ActiveState which is pretty much precompiled bins.

I know: not well... That returns MSWin324.0, which is clearly not true for my platform (ActivePerl 5.6.1 on WinXP).

Looks to me like [MS]Win32/4.0 is the system that AS compiled the binaries on (since Config.pm is created during compile for the purpose of recording such information). Because Win32 binaries are compatible across Windows versions this means that relying on that is misleading.

However, the shell command 'ver' on my machine emits "Microsoft Windows 2000 [Version 5.00.2195]", so if you need more granular information about which Windows version you are running on, you might try that.
