# notification: notifications handling

Notifications can be retrieved, expired or created with the `notification` commands.

## add

Add and broadcast a new notification. Only admin profiles can add a notification.

It can be used for service announcement, such as planned maintenance.

To make an announcement to all profiles, use the `-g, --is-global`. Note that such global notification aren’t deleted when using expire command: you have either to use `-e EXPIRE_AT, --expire-at EXPIRE_AT` to set an expiration date, or to delete them manually with delete.

### example

Add a global service announcement to indicate that the server will be shut down. The expiration date is set so that the notification will be expired after expected end of maintenance:

    $ li notification add service "Server will be shut down for maintenance." -P HIGH -g -e "2023-10-22"

## get

Retrieve notification for current profile. If `-f, --follow` argument is used, the CLI will continue to run and show any new incoming notification.

### examples

Louise wishes to obtain her current notifications and display any new notifications as they are issued:

    $ li notification get -f

Louise wants to see all her chat notifications which are at least of high priority (this includes urgent ones):

    $ li notification get -t chat -P HIGH

## delete

Delete a notification by its ID. The notification must belong to the profile doing the request.

If `-g, --is-global` is used, a global notification is to be deleted. Only admins can delete a global notification.

### example

Louise (who is an admin) wants to delete a previous global service announcement with ID `123`:

    $ li notification delete -g 123

## expire

Delete expired notification (the ones with an expiration date set).

If `-l TIME_PATTERN, --limit TIME_PATTERN` is used, also delete notification which have been created before the given limit. Some notifications can’t be deleted this way: if they are global, or if they require a user action. Using `now` as time pattern will clear all the notifications that can be deleted.

By default, only notifications of requesting profile are deleted (except for expired ones which are always deleted). If `-a, --all` is used, notification for all profiles can be deleted. This option is notably useful to schedule automatic notification cleaning.

### example

Louise want to expire notification for all profiles that are older than 7 days:

    $ li notification expire -a -l "7 days ago"
