narashima has asked for the wisdom of the Perl Monks concerning the following question:

Revered Monks,

Could you please tell me how I can identify if my perl script is running on Windows or Unix(Solaris)?

I want to make the script different way depending on the OS it is running on.

Thanks!

    $^O (letter O, not zero) will tell you which OS perl was built under, which in your case, should be good enough (it isn't very good at distinguishing between Windows variants).

    You can read all about it in perlvar.

      If the program needs to know the flavour of Windows, it can call Win32's GetOSVersion after ascertaining it's running on a Win32 machine.

    Hello,

    To extrapolate on what FunkyMonk said..
    I had somewhat of the same question answered by Fletch here.. Re: OS400 Pace - architecture?

    The $^O variable only contains the architecture the platform was built on. If you want to know on which platform it's running try using uname with backticks on a Unix platform and/or ver on a Windows box.

      On Linux, the pseudo file /proc/version may provide flavor information. Cheers.
