Syntax: show [alias-name [attributes]]

    The show command is used to list the contents of a database. The
    optional attributes keyword, when supplied, causes the attributes
    associated with each alias to also be displayed:

    db> add postmaster "system@thor.example.com"
    [Entry added to database]
    db> show postmaster attributes
    Key         Value
    ----------  -----------------------------
    postmaster  system@thor.example.com
    Attributes: private,expand,block-receipts,mail-address
    [1 entries shown]
    db>

    The alias name specification can contain wild cards. To see
    all entries with the mail-address attribute, issue the command
    "show"; to see absolutely all entries, first issue the command
    "override on" followed by the command "show"
