OpenExtensions for z/VM

A list of the Single UNIX Specification commands by category

This list organizes the Single UNIX Specification commands and utilities (all supported by OpenExtensions for z/VM) by user task categories.

The following list presents OpenExtensions shell commands and utilities grouped by the task a user might want to perform. Similar tasks are organized together. Stub commands (cancel, cu and lpstat) are not listed because their functions are not supported by OpenExtensions.

The list shows the command name and its function. Functions marked with "|" were added in VM/ESA 2.3.0.
