The /dev/null device on windows is now NIL That is not true. The nul device on wihdows is any file with a name that (without any extension) equals 'nul' in any case.

Several resources suggest that `NUL` is a reserved file name, not `NIL`. I don't have a windows at hand to test it, but I'd guess it's actually NUL that is equivalent to UNIX' /dev/null. Perl 6 - the future is here, just unevenly distributed	[reply] [d/l] [select]

Do you have a reference for that? I am not able to verify that this is the case. If it is, ouch (unnecessary backward compatible breakage). In fact, my testing from a Windows 7 cmd prompt and perl script seem to disprove your assertion. --MidLifeXis	[reply]
