IBM z/OS V2R2: Unix Systems Services

Book Description

This IBM® Redbooks® publication familiarizes you with the technical changes that were introduced into the UNIX System Services areas with IBM z/OS® V2R2.

This book is one of a series of IBM Redbooks publications that take a modular approach to providing information about the updates that are included within z/OS V2R2. This approach has the following goals:

- Provide modular content
- Group the technical changes into a topic
- Provide a more streamlined way of finding relevant information that is based on the topic

We hope you find this approach useful. We value your feedback.
