No, as it is specific to the Rakudo / nqp implementation of Perl 6.

You can find it here in rendered format:

That is not under https://docs.perl6.org/, I presume.

Perhaps Zoffix is willing to take a PR for an IO::Path.nlinks method as part of 
the IO grant.

Re: zef, zef-j, zef-m

[Brent Laabs]

This works without a module on Rakudo:

use nqp;
my $path = "foo".IO;
my $hardlink-count =  nqp::stat($path.absolute,
nqp::const::STAT_PLATFORM_NLINKS);

Re: zef, zef-j, zef-m

[Fernando Santagata]

The three files are already hard-linked, no need for soft links.

BTW, is there a way to detect hard links in Perl6?
Perl5 "stat" operator returns an array whose fourth element is the number
of hard links of a file, but I don't see anything like that in the Perl6
docs.

[Parrot Raiser]

If they are really identical, might it be an idea to use symbolic
links for 2 of them?
That would reduce the code to be stored, maintained, and transmitted,
and make it blatantly obvious if different versions are required.

zef, zef-j, zef-m

[Gabor Szabo]

Hi,

I've just noticed that in /Applications/Rakudo/share/perl6/site/bin/ I
have 3 copies
of every script. One with a -j and one with a -m at the end just as for zef:

zef
zef-j
zef-m

The files seem to be identical.

Why are there 3 and what is their purpose?
