NAME
       sg_read_buffer - send a SCSI READ BUFFER command

SYNOPSIS
       sg_read_buffer [--help] [--hex] [--id=ID] [--length=LEN] [--mode=MO] [--offset=OFF] [--raw] [--verbose] [--version] DEVICE

DESCRIPTION
       Sends  a  SCSI  READ  BUFFER  command  to the DEVICE, and if there is a response either decodes it, prints it in hexadecimal or sends it in
       binary to stdout. If a response is received for a "descriptor" mode then, in the absence of --hex and --raw, it is  decoded.  Response  for
       non-descriptor modes are output in hexadecimal unless the --raw option is given.

OPTIONS
       Arguments to long options are mandatory for short options as well.

       -h, --help
	      output the usage message then exit. If used multiple times also prints the mode names and their acronyms.

       -H, --hex
	      output the response in hexadecimal.

       -i, --id=ID
	      this option sets the buffer id field in the cdb. ID is a value between 0 (default) and 255 inclusive.

       -l, --length=LEN
	      where  LEN  is the length, in bytes, that is placed in the "allocation length" field in the cdb. The default value is 4 (bytes). The
	      device may respond with less bytes.

       -m, --mode=MO
	      this option sets the mode field in the cdb. MO is a value between 0 (default) and 31 inclusive. Alternatively an abbreviation can be
	      given.  To list the available mode abbreviations given an invalid one (e.g. '--mode=xxx').

       -o, --offset=OFF
	      this option sets the buffer offset field in the cdb. OFF is a value between 0 (default) and 2**24-1 . It is a byte offset.

       -r, --raw
	      if a response is received then it is sent in binary to stdout.

       -v, --verbose
	      increase the level of verbosity, (i.e. debug output).

       -V, --version
	      print the version string and then exit.

NOTES
       All  numbers  given  with options are assumed to be decimal.  Alternatively numerical values can be given in hexadecimal preceded by either
       "0x" or "0X" (or has a trailing "h" or "H").

EXIT STATUS
       The exit status of sg_read_buffer is 0 when it is successful. Otherwise see the sg3_utils(8) man page.
