The most recent version (that I have) of the Shell Spec is 2.2. That version lists both "ping" and "ping6", and the synopsis for "ping" is: Ping [-n count] [-l size] [-s SourceIp] TargetIp I recommend that you (a) refresh your shell spec, (b) always build the Shell application from source, in your platform DSC. ... In general, I wish new versions of the specifications (UEFI, PI, edk2), and new whitepapers in the "Tour Beyond BIOS" series, were announced on edk2-devel :( Tony, do you think you could grease some gears for such announcements?
