Usage: sg_rep_zones  [--domain] [--find=ZT] [--force] [--help] [--hex]
                     [--inhex=FN] [--json[=JO]] [--js_file=JFN]
                     [--locator=LBA] [--maxlen=LEN] [--num=NUM]
                     [--partial] [--raw] [--readonly][--realm]
                     [--report=OPT] [--start=LBA] [--statistics]
                     [--verbose] [--version] [--wp] DEVICE
  where:
    --domain|-d        sends a REPORT ZONE DOMAINS command
    --find=ZT|-F ZT    find first zone with ZT zone type, starting at LBA
                       if first character of ZT is - or !, find first
                       zone that is not ZT
    --force|-f         bypass some sanity checks when decoding response
    --help|-h          print out usage message, use twice for more help
    --hex|-H           output response in hexadecimal; used twice
                       shows decoded values in hex
    --inhex=FN|-i FN    decode contents of FN, ignore DEVICE
    --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
    --locator=LBA|-l LBA    similar to --start= option
    --maxlen=LEN|-m LEN    max response length (allocation length in cdb)
                           (def: 0 -> 8192 bytes)
    --num=NUM|-n NUM    number of zones to output (def: 0 -> all)
    --partial|-p       sets PARTIAL bit in cdb (def: 0 -> zone list
                       length not altered by allocation length in cdb)
    --raw|-r           output response in binary
    --readonly|-R      open DEVICE read-only (def: read-write)
    --realm|-e         sends a REPORT REALMS command
    --report=OPT|-o OP    reporting options (def: 0: all zones)
    --start=LBA|-s LBA    report zones from the LBA (def: 0)
                          need not be a zone starting LBA
    --statistics|-S    gather statistics by reviewing zones
    --verbose|-v       increase verbosity
    --version|-V       print version string and exit
    --wp|-w            output write pointer only

Sends a SCSI REPORT ZONES, REPORT ZONE DOMAINS or REPORT REALMS command.
By default sends a REPORT ZONES command. Give help option twice
(e.g. '-hh') to see reporting options enumerated.

Options (22)

Option	Description	Source
`--find, -F` ZT\|-F	find first zone with ZT zone type, starting at LBA if first character of ZT is - or !, find first zone that is not ZT	help + man
`--inhex, -i` FN\|-i	where FN is a file name whose contents are assumed to be ASCII hexadecimal.	help + man
`--json` JO]\|-j[=JO	output in JSON instead of plain text Use --json=? for JSON help	help
`--js-file, -J` JFN\|-J	JFN is a filename to which JSON output is written (def: stdout);	help + man
`--locator, -l` LBA\|-l	where LBA plays a similar role as it does in --start=LBA.	help + man
`--maxlen, -m` LEN\|-m	max response length (allocation length in cdb) (def: 0 -> 8192 bytes)	help + man
`--num, -n` NUM\|-n	where NUM is the (maximum) number of zone descriptors to print out.	help + man
`--report, -o` OPT\|-o	where OPT will become the contents of the REPORTING OPTION field in the cdb.	help + man
`--start, -s` LBA\|-s	report zones from the LBA (def: 0) need not be a zone starting LBA	help + man
`-b, --brief`	even though a ZBC disk will typically limit the size of the response to the REPORT ZONES command (e.g. due to the "allocation length" field), this may still be potentially a lot of output. (in the manual page but not in --help)	man
`-d, --domain`	send or decode the SCSI REPORT ZONE DOMAINS command. (in the manual page but not in --help)	man
`-f, --force`	when decoding the response to this command, certain sanity checks are done and if they fail a message is sent to stderr and a non-zero exit status is set. (in the manual page but not in --help)	man
`-h, --help`	output the usage message then exit. (in the manual page but not in --help)	man
`-H, --hex`	output the response in hexadecimal to stdout. (in the manual page but not in --help)	man
`-p, --partial`	set the PARTIAL bit in the cdb. (in the manual page but not in --help)	man
`-r, --raw`	output response in binary (to stdout) unless the --inhex=FN option is also given. (in the manual page but not in --help)	man
`-R, --readonly`	open the DEVICE read-only (e.g. in Unix with the O_RDONLY flag). (in the manual page but not in --help)	man
`-e, --realm`	send or decode the SCSI REPORT REALMS command. (in the manual page but not in --help)	man
`-S, --statistics`	reviews all or a limited number of report zones, collects statistics and prints them (on stdout). (in the manual page but not in --help)	man
`-v, --verbose`	increase the level of verbosity, (i.e. debug output). (in the manual page but not in --help)	man
`-V, --version`	print the version string and then exit. (in the manual page but not in --help)	man
`-w, --wp`	print the write pointer (in hex) only. (in the manual page but not in --help)	man

Exit status (1) from the manual page
