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: ). 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/ $RE_OS_IS_POSIX Current value: qr/\A(?:aix|beos|cygwin|darwin|dragonfly|freebsd|gnu|gnukfreebsd|haiku|hpux|interix|iphoneos|irix|linux|midnightbsd|minix|mirbsd|msys|netbsd|openbsd|sco|sco_sv|solaris|sunos|svr4|svr5|unicos|unicosmk)\z/ $RE_OS_IS_UNIX Current value: qr/\A(?:aix|android|bsdos|bitrig|dgux|dynixptx|cygwin|darwin|dragonfly|freebsd|gnu|gnukfreebsd|hpux|interix|iphoneos|irix|linux|machten|midnightbsd|mirbsd|msys|netbsd|next|nto|openbsd|qnx|sco|sco_sv|solaris|sunos|svr4|svr5|unicos|unicosmk)\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. HOMEPAGE Please visit the project's homepage at . SOURCE Source repository is at . BUGS Please report any bugs or feature requests on the bugtracker website When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature. 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".
