3. Pywbemlistener command

The pywbemlistener command can run and manage WBEM listeners.

Each listener is a process that executes the pywbemlistener run command to receive WBEM indications sent from a WBEM server.

A listener process can be started with the pywbemlistener start command and stopped with the pywbemlistener stop command.

There is no central registration of the currently running listeners. Instead, the currently running processes executing the pywbemlistener run command are by definition the currently running listeners. Because of this, there is no notion of a stopped listener nor does a listener have an operational status.

This section describes the command line interface of the pywbemlistener terminal command.

The pywbemlistener command is invoked from a command line terminal with a command and arguments/options as shown here:

$ pywbemlistener [GENERAL-OPTIONS] COMMAND [COMMAND-OPTIONS] [ARGUMENTS]
or
$ pywbemlistener [GENERAL-OPTIONS] COMMAND [ARGUMENTS] [COMMAND-OPTIONS]

Where the components are:

GENERAL-OPTIONS - General options apply to all pywbemlistener commands. They start with - or --. See Pywbemlistener general options
COMMAND - A name of a command to be executed. See Pywbemlistener commands
ARGUMENTS - Arguments may be defined for specific commands. Arguments do not have preceeding dashes. Arguments name the target listener for commands that execute against a single listener (ex. start lis1)
COMMAND-OPTIONS - Options that apply only to a particular COMMAND. Options are prefixed with the characters - for the short form or -- for the long form (ex. -n or --namespace).

Pywbemistener supports tab-completion. Tab-completion is available with some command shells and only when activated for the shell type after pywbemlistener installation. It is available for bash, zsh, and fish shells.

Tab-completion is available in pywbemcli for:

All command names
All general and command specific option names
command arguments (i.e. listener names)
