====== Display configuration setting ======

===== Synopsis =====

    show <setting>

===== Examples =====

=== Display the IP address for the interface "net0" ===

    show net0/ip

=== Display the boot filename ===

    show filename

=== Display DHCP option 42 as an IPv4 address ===

    show 42:ipv4  # Option 42 - NTP server address

===== Description =====

Display value of the specified configuration [[:settings|setting]].

The value will be displayed according to the type specified as part of the setting name.  For example, an IPv4 address assigned to the network interface "net0" can be displayed as a series of bytes:

    iPXE> show net0/ip:hex
    net0/ip:hex 0a:00:00:64

or as an unsigned integer:

    iPXE> show net0/ip:uint32
    net0/ip:uint32 = 0xa000064

or as an IPv4 address:

    iPXE> show net0/ip:ipv4
    net0/ip:ipv4 = 10.0.0.100

If no type is explicitly specified, then the setting's default type will be used.

The origin (and type) of the setting will be displayed along with the setting's value.  For example:

    iPXE> show net0/ip
    net0.dhcp/ip:ipv4 = 192.168.0.100

In this example you can see that the IP address originates from the settings block ''net0.dhcp'' (i.e. it is an address assigned by a DHCP server), and that it has a type of ''ipv4''.

===== Notes =====

You can use the ''[[:cmd:config]]'' command to browse through settings interactively.

To display only the value of a setting, without also displaying its origin and type, you can use the ''[[:cmd:echo]]'' command.  For example:

    iPXE> echo ${net0/ip}
    192.168.0.100
