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.

Who should read this information?

Application programmers, system programmers, and users who are working on a z/OS system and are using the shell.
