3.1  CLI Overview

The command line interface (CLI) provides a text-based interface for SEA.

Security and the CLI

In order to run any of the commands described in this chapter, you must be a privileged user. Refer to Section 1.5 for information on the permissions required for your operating system.

Clusters and the CLI

Even if SEA is installed on a cluster, commands only impact the local node. Thus, if you want to modify an entire cluster you will need to perform the desired operation on each node.

Standalone CLI

The Director is not required to run all the CLI commands. The following CLI functions can be performed without the Director:

Since these operations do not use the Director, messages that would otherwise be written to the Director's log files are included in the output for the command. The messages shown remain subject to the logging level. Refer to Section 1.12 for more information on log messages.

Table 3–1 describes the conventions used to show CLI commands in this manual.
