Re: Documentation on "dh" shell command

["Carsey, Jaben" <jaben.carsey@intel.com>]

Thanks Andrew.  I had been confused by the "column" on the non-SFO output format.

Maybe we should add a better description for the generic output. Like:
<HandleIdentifier> < ProtocolBasicInfo > [*<ProtocolBasicInfo >]

Note that some protocols (like DevicePath in the example below) have additional dynamic content in their basic info, while most just have protocol name.

Hi Jaben

Dh says like
14C: IPv4
14D: SimpleFileSystem DiskIO BlockIO DevicePath(..R,0x7D5FDC4F,0x20000,0xA001))


The 1st hex number is a handle number, basically a User Interface name for the handle. The names after the colon represent protocol instances on the handle.

You can get more info about the protocols by dumping the handle so: dh 14D

Thanks,

Andrew Fish

But documentation is not saying what is column 1, 2 and so on
What I am looking for description of output of dh command with various options

Thanks
Udit

Udit,

There are some examples in the shell spec just before the table you found,
but no exact output requirement for dh. What handle information are you
looking for?  Maybe we can add that to the dynamic help for the command
(the stuff users can see from "dh =?").

Hi,
Could you help me, where I can get documentation on output of dh shell
command.
UEFI_Shell_Spec_2_2.pdf , table 18 is giving details of sfo option
only for each column.

Thanks
Udit
