Usage: sg_stream_ctl [-brief] [--close] [--ctl=CTL] [-get] [--help]
[--hex] [--id=SID] [--inhex=FN] [--json[=JO]]
[--js-file=JFN] [--maxlen=LEN] [--open] [--raw]
[--readonly] [--verbose] [--version] DEVICE
where:
--brief|-b for open, output assigned stream id to stdout, or
-1 if error; for close, output 0, or -1; for get
output list of stream id, 1 per line
--close|-c close stream given by --id=SID
--ctl=CTL|-C CTL CTL is stream control value, (STR_CTL field)
1 -> open; 2 -> close
--get|-g do GET STREAM STATUS command (default if no other)
--help|-h print out usage message
--hex|-H print 'get' output in hex
--id=SID|-i SID for close, SID is stream_id to close; for get,
list from and including this stream id
--inhex=FN|-I FN input taken from file FN rather than DEVICE,
assume it is ASCII hex or, if --raw, in binary
--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
--maxlen=LEN|-m LEN length in bytes of buffer to receive data-in
(def: 8 (for open and close); 252 (for get,
but increase if needed)
--open|-o open a new stream, return assigned stream id
--raw|-R --hex output or --inhex= input: in binary
instead of hex
--readonly|-r open DEVICE read-only (if supported)
--verbose|-v increase verbosity
--version|-V print version string and exit
Performs a SCSI GET STREAM STATUS or STREAM CONTROL command. If --open,
--close or --ctl=CTL given (only one) then performs STREAM CONTROL
command. If --get or no other selecting option given then performs a
GET STREAM STATUS command. A successful --open will output the assigned
stream id to stdout (and ignore --id=SID , if given).
Options (16)
| Option | Description | Source |
|---|
--ctl, -C CTL|-C | CTL is the value placed in the STR_CTL field of the STREAM CONTROL command (cdb). | help + man |
--id, -i SID|-i | SID is a stream id, a value between 1 and 65535. | help + man |
--inhex, -I FN|-I | input taken from file FN rather than DEVICE, assume it is ASCII hex or, if --raw, in binary | 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 |
--maxlen, -m LEN|-m | length in bytes of buffer to receive data-in (def: 8 (for open and close); | help + man |
-b, --brief | this option reduces the output of the GET STREAM STATUS command to just one number (in decimal) per line sent to stdout. (in the manual page but not in --help) | man |
-c, --close | selects the STREAM CONTROL command and sets STR_CTL<--0x2 (i.e. 'close'). (in the manual page but not in --help) | man |
-g, --get | selects the GET STREAM STATUS command. (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 | (in the manual page but not in --help) | man |
-o, --open | selects the STREAM CONTROL command and sets STR_CTL<--0x1 (i.e. 'open'). (in the manual page but not in --help) | man |
-r, --readonly | this option sets a 'read-only' flag when the underlying operating system opens the given DEVICE. (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 |
-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 |
