Petals CLI realizes the following use-cases.

h2. Petals CLI capabilities about script and shell usages

h3. Interactive console

Launching the Petals CLI with the following command line starts an interactive console with a prompt where the user can enter commands:
{code}
> ./petals-cli.sh -C

Type 'help' for help.
------------------------------------------------------------------------------
petals-cli>
{code}

This command is wrapped by another shell: petals-cli-console.sh

h3. Execution of a Petals CLI command directly on the command line

{code}
> ./petals-cli.sh -c help <command>

usage: <command> <command-arguments>

<command description>
>
{code}
where:
- {{<command>}} is the command for which we want to get help

- {{<command-description}} is a text explaining the command

h3. Getting help on available commands and on a command in interactive mode

The list of available command can be get using the command '{{help}}' without argument:

- the return values of command {{isParsingErrorReturned}}, {{isExecutionErrorReturned}} and {{isNoErrorReturned}} are re-intialized when invoking command. Only the error of the last command execution can be checked.
- the attribute {{lastErrorCode}} is an argument of the command {{exit}} to return the return code of the last executed command.

h2. Connection to a Petals node

h3. Connection options from the command line

All parameters needed to a JMX connection to a remote Petals node must be configurable on the command line as options:
{code}
> ./petals-cli.sh -h <host> -n <port> -u <user> -p <password> -c <command>
> ./petals-cli.sh -h <host> -n <port> -u <user> -p <password> -C
Conected on <host1>:<port1> with <user1>
petals-cli>
{code}

h3. Interacting with several Petals node without exiting Petals CLI

In interactive mode or script mode, we should be able to close a connection and open another one without leaving Petals CLI. This is done by commands '*{{close}}*' and '*{{open}}*'. If no arguments are set on command 'open', default values (localhost:7700, login=petals, pwd=petals) are used:
{code}
> ./petals-cli.sh -C

Type 'help' for help.
------------------------------------------------------------------------------
petals-cli> open <user1>:<password1>@<host1>:<port1>
Conected on <host1>:<port1> with '<user1>'
petals-cli> close
petals-cli> open
Conected on localhost:7700 with 'petals'
{code}

h3. Default connection

By default (if no argument or option is set):
- In mode 'console', the connexion is establish on command '*{{open}}*' to localhost:7700 with credentials 'petals/petals',
{code}
> ./petals-cli.sh -C

Type 'help' for help.
------------------------------------------------------------------------------
petals-cli> open
Conected on localhost:7700 with 'petals'
{code}
- In mode 'command line', connexion parameter are mandatory
{code}
> ./petals-cli.sh -h <host> -n <port> -u <user> -p <password> -c <command>
{code}

{code}

h2. Petals CLI commands

h3. Command '{{deploy}}'

h4. Installation/Deployment and start of an artifact in one command

Petals CLI is able to install/deploy and start a JBI artifact without distinction between shared-library, component and service assembly using the following command:
{code}
deploy <artifact-file> [<configuration-file> | <configuration-properties>]
{code}
where:
- {{<artifact-file>}} is the local file name or the URL of the artifact to install or deploy and start
- {{<configuration-file>}} is the local file name or the URL of the properties file used to configure the artifact. This argument is used only if the component is a component. It has no sens for other artifacts. This argument is exclusive with {{<configuration-properties>}}.
- {{<configuration-properties>}} is a list of '{{<property-name>=<property-value>}}', separated by space, where {{<property-name>}} is the name of the property to configure with {{<property-value>}}. This argument is used only if the component is a component. It has no sens for other artifacts. This argument is exclusive with {{<configuration-file>}}.

h4. Installation/Deployment of an artifact located into a Maven repository

Petals CLI is able to install/deploy and start an JBI artifact located into a Maven repository using the following command:
{code}
deploy <maven-artifact> [<configuration-file> | <configuration-properties>]
{code}
where:
- {{<maven-artifact>}} is the Maven identifiers of the artifact to install: {{group-id:artifact-id:version[:classifier]}}. If needed, the Maven repository is to define in the Maven configuration file ($HOME/.m2/settings.xml)
- {{<configuration-file>}} is the local file name or the URL of the properties file used to configure the artifact. This argument is used only if the component is a component. It has no sens for other artifacts. This argument is exclusive with {{<configuration-properties>}}.
- {{<configuration-properties>}} is a list of '{{<property-name>=<property-value>}}', separated by space, where {{<property-name>}} is the name of the property to configure with {{<property-value>}}. This argument is used only if the component is a component. It has no sens for other artifacts. This argument is exclusive with {{<configuration-file>}}.

h4. Installation/Deployment and start in mass

> ./petals-cli.sh -C

Type 'help' for help.
------------------------------------------------------------------------------
petals-cli> deploy /tmp
Are you sure you want to deploy all artifacts of directory '/tmp' (Y/n) ?
{code}

If the argument {{<artifact-file>}} of the command {{deploy}} is a local directory, all artifacts of the directory are deployed. In this case a confirmation is expected, except if the flag 'yes' is set on the command line. A confirmation message is displayed in the mode 'console', except is the flag 'yes' is set on the command line.

h3. Command '{{undeploy}}'

h4. Uninstallation/Undeployment and stop of an artifact in one command

Petals CLI is able to stop and uninstall/undeploy a JBI artifact without distinction between shared-library, component and service assembly using the following command:
{code}
undeploy [ <artifact-file> | [<artifact-type> <artifact-id>] ]
{code}
where:
- {{<artifact-file>}} is the local file name or the URL of the artifact to undeploy
- {{<artifact-type>}} is the nature (SL, component, SA) of the artifact to undeploy
- {{<artifact-id>}} is the JBI identifier of the artifact to undeploy

h4. Uninstallation/Undeployment and stop in mass

> ./petals-cli.sh -C

Type 'help' for help.
------------------------------------------------------------------------------
petals-cli> undeploy
Are you sure you want to undeploy all artifacts of the Petals node (Y/n) ?
{code}

If no arguments is set on command {{undeploy}}, all artifacts are undeployed. In this case a confirmation is expected, except if the flag 'yes' is set on the command line. A confirmation message is displayed in the mode 'console', except is the flag 'yes' is set on the command line.

h3. Command '{{exit}}'

h4. Exit the mode 'console'

To exit the mode 'console', use the command '*{{exit}}*'. If a number is set as argument, it is used as return code otherwise, the return code 0 is used:
{code}
> ./petals-cli.sh -C

Type 'help' for help.
------------------------------------------------------------------------------
petals-cli> exit
> echo $?
0
> ./petals-cli.sh -C

Type 'help' for help.
------------------------------------------------------------------------------
petals-cli> exit 1
> echo $?
1
{code}

h4. Interrupt a flow of commands

EOF
{code}

h4. Ending a flow of commands

echo $?
0
{code}

h3. Showing what is installed

h4. Showing installed JBI artefacts

All installed JBI artefacts can be listed using the command '*{{list \[<artifact-pattern> \[artifact-type\]\]}}*':
{code}
> ./petals-cli.sh -c list
petals-bc-soap Started BC
petals-se-bpel Started SE
soap-consume-provide Started SA
su-SOAP-EchoService-consume Started SU
su-SOAP-EchoService-provide Started SU
{code}
where:
- {{<artifact-pattern>}} is an optional RegExp pattern to filter the content of the returned list. All JBI artifact returned must have a JBI identifier matching the pattern. If not pattern is defined, all installed artifacts are returned.
- {{<artifact-type>}} is one of the following values: SL, BC, SE, SA, SU, used to restrict the returned list
The command displays (caution to the padding) for each artifact:
- its JBI identifier
- its current status,
- its type (SL, BC, SE, SA, SU)

h3. Getting versions

h4. Getting the versions of the Petals CLI

To get the version of Petals CLI, the version of the JVM running Petals CLI, and its operating system, use the option '-V':
