$OSNAME

$^O

The name of the operating system under which this copy of Perl was built, as determined during the configuration process. The value is identical to $Config{'osname'}. See also "Config" in the Perl C API and Internals Manual and the -V command-line switch documented in 3.

In Windows platforms, $^O is not very helpful: since it is always MSWin32, it doesn't tell the difference between 95/98/ME/NT/2000/XP/CE/.NET. Use Win32::GetOSName() or Win32::GetOSVersion() (see Win32 and 28) to distinguish between the variants.
