[3] (lldb) = efi_symbols -h
Usage: = efi_symbols [options]

Stand = alone script that can load EFI PE/COFF and TE image = symbols.

Options:
  -p, --pc      =         Load symbols for pc
  -f, --frame           Load = symbols for current stack frame
  = -a ADDRESS, --address=3DADDRESS
  =                     =   Load symbols for image at address
  = -r RANGE, --range=3DRANGE
  =                     =   How far to search backward for start of PE/COFF = Image
  -t, --terse       =     Only display filenames not paths
  -h, --help            = Show help for the command
