               [--version] DEVICE
  where the main options are:
    --ALL|-A        fetch and decode all log pages and subpages
    --all|-a        fetch and decode all log pages, but not subpages; use
                    twice to fetch and decode all log pages and subpages
    --brief|-b      shorten the output of some log pages
    --enumerate|-e    enumerate known pages, ignore DEVICE. Sort order,
                      '-e': all by acronym; '-ee': non-vendor by acronym;
                      '-eee': all numerically; '-eeee': non-v numerically
    --filter=FL|-f FL    FL is parameter code to display (def: all);
                         with '-e' then FL>=0 enumerate that pdt + spc
                         FL=-1 all (default), FL=-2 spc only
    --full|-F       drill down in application client log page
    --help|-h       print usage message then exit. Use twice for more help
    --hex|-H        output response in hex (default: decode if known)
    --inhex=FN|-i FN    FN is a filename containing a log page in ASCII hex
                        or binary if --raw also given. --inhex=FN also accepted
    --in=FN|-i FN    same as --inhex=FN
    --json[=JO]|-j[=JO]    output in JSON instead of plain text
                           Use --json=? for JSON help
    --js-file=JFN|-J JFN    JFN is a filename to which JSON output is
                            written (def: stdout); truncates then writes
    --list|-l       list supported log pages; twice: list supported log
                    pages and subpages page; thrice: merge of both pages
    --page=PG|-p PG    PG is either log page acronym, PGN or PGN,SPGN
                       where (S)PGN is a (sub) page number
    --temperature|-t    decode temperature (log page 0xd or 0x2f)
    --transport|-T    decode transport (protocol specific port 0x18) page
    --vendor=VP|-M VP    vendor/product abbreviation [or number]
    --verbose|-v    increase verbosity

Performs a SCSI LOG SENSE (or LOG SELECT) command and decodes the response.
If only DEVICE is given then '-p sp' (supported pages) is assumed. Use
'-e' to see known pages and their acronyms. For more help use '-hh'.
