NAME
   Perl::osnames - List possible $^O ($OSNAME) values, with description

VERSION
   This document describes version 0.122 of Perl::osnames (from Perl
   distribution Perl-osnames), released on 2020-02-13.

DESCRIPTION
   This package contains $data which lists possible values of $^O along
   with description for each. It also provides some helper functions.

 Tags
   *   unix

       Unix-like operating systems. This currently excludes beos/haiku.

   *   bsd

       BSD-derived Unix operating systems.

   *   sysv

       SysV-derived Unix operating systems.

   *   posix

       For POSIX-compliant OSes, including fully-, mostly-, and
       largely-compliant ones (source:
       <http://en.wikipedia.org/wiki/POSIX>).

       From what I can gather, dec_osf is not POSIX compliant, although
       there is a posix package for it.

VARIABLES
   None are exported by default, but they are exportable.

 $data
   An arrayref of records (arrayrefs), each structured as:

    [$name, \@tags, $description]

 $RE_OS_IS_KNOWN
   Current value:

    qr/\A(?:aix|amigaos|android|bsdos|beos|bitrig|dgux|dos|dynixptx|cygwin|darwin|dec_osf|dragonfly|freebsd|gnu|gnukfreebsd|haiku|hpux|interix|iphoneos|irix|linux|MacOS|machten|midnightbsd|minix|mirbsd|mpeix|msys|MSWin32|netbsd|next|nto|openbsd|os2|os390|os400|posix-bc|qnx|riscos|sco|sco_sv|solaris|sunos|svr4|svr5|unicos|unicosmk|vmesa|VMS|vos)\z/

FUNCTIONS
   None are exported by default, but they are exportable.

 is_posix([ $os ]) => bool
   Check whether $os (defaults to $^O if not specified) is POSIX (checked
   by the existence of "posix" tag on the OS's record in $data). Will
   return 0, 1, or undef if $os is unknown.

 is_unix([ $os ]) => bool
   Check whether $os (defaults to $^O if not specified) is Unix (checked by
   the existence of "unix" tag on the OS's record in $data). Will return 0,
   1, or undef if $os is unknown.

SEE ALSO
   perlvar

   Config

   Perl::OSType, a core module. You should probably use this module
   instead. Currently the difference between this module and Perl::osnames:
   1) Perl::osnames currently doesn't list beos/haiku as Unix, but POSIX;
   2) Perl::osnames provides more tags (like sysv, bsd, posix) and
   description.

   Devel::Platform::Info

   The output of "perl -V"

   App::osnames, the original reason for Perl::osnames. With this CLI tool
   you can grep OS names by name, tag, or description, e.g. "osnames
   solaris" or "osnames posix".
