NAME

Devel::CheckOS::Families - what OS "families" are supported "out of the box" by Devel::CheckOS and Devel::AssertOS?

CONTENTS

WHAT IS AN OS FAMILY

Computing platforms fall into several categories. For example, there is the category of Unix-a-likes. Each of these categories is a family. A platform can fall into several families.

THE Unix FAMILY

Broadly speaking, these are platforms where:
Devices are represented as pseudo-files in the filesystem
Symlinks and hardlinks are supported in at least some filesystems
‘‘Unix-style’’ permissions are supported That is, there are seperate read/write/execute permissions for file owner, group and anyone. This implies the presence of multiple user accounts and user groups. Permissions may not be supported on all filesystems.
The filesystem has a single root
The C API for the operating system is largely POSIX-compatible

THE Linux FAMILY

This includes both ordinary Linux and Android. Plain old Linux will match ’Linux’. Android will match both that and ’Android’.

THE MicrosoftWindows FAMILY

This includes any version of Windows and also includes things like Cygwin which run on top of it.

THE DEC, Sun, and Apple FAMILIES

These include any OS written by, respectively, DEC, Sun, and Apple. They exist because, while, eg, Mac OS Classic and Mac OS X are very different platforms, they do support some unique features - such as AppleScript.

THE Realtime FAMILY

This is for all real-time OSes. So far, it only includes QNX.

THE EBCDIC FAMILY

OSes which use EBCDIC instead of ASCII.
