# info: retrieve various information

`info` groups subcommands used to retrieve read-only informations.

## disco

Display discovery information, including external discovery (see XEP-0030 and XEP-0215 for details). This can be used to check which features you server or a service is offering, which items are available (items can be services like chat room, gateways, etc), ans which external services (i.e. non-XMPP services) are proposed.

You only have to specify the jid of the entity to check, and optionally a node. If a node is specified, external services won’t be retrieved even if `all` is used (as external services don’t have the notion of “node”).

By default everything is requested (infos, items and external services), but you can restrict what to request by using `-t {infos,items,both,external,all}, --type {infos,items,both,external,all}` where `both` means infos and items, and `all` mean than + external services.

### example

Request infos, items and external services from a server:

    $ li info disco example.org

## version

Request software version of an entity. You only need to specify the jid of the entity as positional argument.

Depending of the software and its configuration, you have software version, software name, and the operating system on which the software is running.

### example

Check version of a server:

    $ li info version example.org

### session

Give information about the session of the given profile. You’ll get the full jid currently used on the server, and the time when the session was started (which may not be the same time as when the connection with the XMPP server was started).

### example

Get session informations:

    $ li info session

### devices

List known devices for an entity. You’ll get resource name, and data such as presence data, and identities (i.e. name and type of the client used).

If entity’s bare jid is not specified, a list of your own devices is returned.

### example

List known devices of Louise:

    $ li info devices louise@example.org

Check if we have other devices connected:

    $ li info devices
