====== Print text to console ======

===== Synopsis =====

    echo [-n] [...]

===== Examples =====

=== Print "hello world" ===

    echo hello world

=== Print the boot filename ===

    echo ${filename}

=== Print the MAC address of interface "net0" ===

    echo MAC address is ${net0/mac}

=== Ask the user to supply a filename ===

    echo -n Enter boot filename:
    read filename
    echo Booting from ${filename}

===== Description =====

Print text to the console.  As with all iPXE commands, any [[:settings]] such as ''${filename}'' will be expanded.  This allows ''echo'' to be used to display the value of iPXE settings.  For example, to display the boot filename obtained via DHCP:

    iPXE> dhcp
    DHCP (net0 52:54:00:12:34:56)... ok
    iPXE> echo ${filename}
    http://boot.ipxe.org/demo/boot.php

If the ''-n'' option is specified, then the trailing newline will not be printed.
