If you application was started from the Shell you can do that
using ShellExecute from 'Library/ShellLib.h'. Example:

EFI_STATUS Status;
EFI_STATUS CommandStatus;
Status = ShellExecute (&gImageHandle, L"memmap", FALSE, NULL,
&CommandStatus);

If you were not started by the Shell you can run a new Shell and tell it to
run your command and exit afterwards using these LoadImage arguments:

-nomap -nostartup -noversion -_exit [CMD OR FILE]

Thanks
Michael
