Maybe the Standards-Part should be separated from the thread? (Last time I requested Thread separation there was a broken thread afterwards in the forum, which might have nothing to do with that, but I just wanted to mention).

I would throw in another question:

Does POSIX contain a programming language environment?
Is there a programming language available in every environment?

In contrast to Linux the situation of HP-UX,Solaris,AIX, ... in terms of easy available and easy installable software for me(as linux-only-user) seems like the availablity of water in the ocean and the desert.

So I'm wondering if there is any programming language installed in those unices so there maybe one programming environment available everywhere. I'm not talking about sh/ksh/bash. I do not consider them as real programming language. Yes, one can write very large shell scripts, but I think it's a mess. Bad maintainability. Slow Speed. High Resource Footprint(New process creatings for most things). Unsafe Programming environment. Inferior programming feature set.

I would imagine perl 5(perl 5 is 25 years old now. Having perl means: just the perl-base, no modules) could be everywhere. Despite being the opposite of my favourite programming language, if I had/wanted to write portable code, perl would be a lot better than any shell. The developer of inxi(hardware information tool,Inxi at github) went that way - inxi a 20,000 line perl script - written targeted at very high compatibility(Before switching to perl he had used bash and gnu awk).

devel::patchperl

Devel::PatchPerl(3pm)					User Contributed Perl Documentation				     Devel::PatchPerl(3pm)

NAME

       Devel::PatchPerl - Patch perl source a la Devel::PPPort's buildperl.pl

VERSION

       version 0.72

SYNOPSIS

	 use strict;
	 use warnings;

	 use Devel::PatchPerl;

	 Devel::PatchPerl->patch_source( '5.6.1', '/path/to/untarred/perl/source/perl-5.6.1' );

DESCRIPTION

       Devel::PatchPerl is a modularisation of the patching code contained in Devel::PPPort's "buildperl.pl".

       It does not build perls, it merely provides an interface to the source patching functionality.

FUNCTION

       "patch_source"
	   Takes two parameters, a "perl" version and the path to unwrapped perl source for that version.  It dies on any errors.

	   If you don't supply a "perl" version, it will attempt to auto-determine the "perl" version from the specified path.

	   If you don't supply the path to unwrapped perl source, it will assume the current working directory.

PLUGIN SYSTEM

       See Devel::PatchPerl::Plugin for details of Devel::PatchPerl's plugin system.

CAVEAT

       Devel::PatchPerl is intended only to facilitate the "building" of perls, not to facilitate the "testing" of perls. This means that it will
       not patch failing tests in the perl testsuite.
