Abstract for z/OS® UNIX System Services Command Reference

Purpose of this information: Information about the z/OS system with the Shell and Utilities feature as well as TSO/E (Time Sharing Option Extensions) commands for using z/OS UNIX System Services (z/OS UNIX) is presented. These features provide an application program interface (API) and a shell interface based on open systems standards.

z/OS UNIX gives the z/OS operating system an open standards interface. It consists of two features:

The Shell and Utilities, which you can use to enter shell commands, write shell scripts, and work with the file system.
The Debugger, which an application programmer can use to debug a z/OS UNIX application program written in the C or C++ languages.

Information about using the shell commands, utilities, and TSO/E commands is also included.

For information about utilities related to ported applications, see http://www.ibm.com/systems/z/os/zos/features/unix/.

Who should read this information? Application programmers, system programmers, and end users working on a z/OS system and using the shell.
