# Overview of Operational Commands

Substation ES operational commands are also known as console commands. You can enter Substation ES operational commands through the Substation ES console interface or remotely from applications.

By using Substation ES operational commands, you can perform the following tasks:

- Show resource usage, statistics, counters, and so forth.
- Connect or disconnect Substation ES Interfaces to back-end systems.
- Terminate Substation ES or its interfaces.
- Initialize data configuration items, such as recipes and triggers, during run time.
- Update a subset of System Initialization Parameters (SIP) during run time.

Commands received from Console Interface are logged and the resultant output is written to the log output medium and the console terminal. The commands are divided into the following four categories:

- Display Commands
- Update Commands
- Initialization Commands
- Control Commands

Except for control commands, you can submit all commands though the batch job `SXJGENSL` or `SXRGENSL` or from a remote user application. You must enter control commands on the z/OS console.

## Command Format

The syntax and terminology are as follows:

command,keyword1,[keyword2,keyword3, ...] [# comments]
Note: You can add a comment, preceded by a space and a number sign (#), at the end of a command.

The first word is the command, followed by one or more keywords, separated by commas. The HELP, SHUT, and TERM commands are exceptions.

Some keywords specify a value with the keyword, as in the following examples:

`RECIPE`=`recipe_name`

`INTF`=`interface_ID`

## Command and Keyword Abbreviations

Some commands and keywords have abbreviated forms. In command descriptions, abbreviations are noted with a vertical bar. The following example shows a command and its abbreviation:

DISCONNECT|DISCONN

You can type either DISCONNECT or DISCONN to specify this command. Similarly, the following example shows a keyword and its abbreviation:

`LISTENERS`|`LSNS`

You can type either `LISTENERS` or `LSNS` to specify this keyword.

## Sample Output

In addition to showing typical usage, some command descriptions provide an example of the output. The following example shows a sample output:
