This may be useful for timing the per command overhead. +Note that TEST UNIT READY has no associated data, just a 6 byte command +and a returned SCSI status value. If the SCSI status value is CHECK +CONDITION then most modern initiators fetch sense data from +the device (i.e. autosense). +.PP +This utility supports two command line syntaxes, the preferred one is +shown first in the synopsis and explained in this section. A later section +on the old command line syntax outlines the second group of options. +.SH OPTIONS +Arguments to long options are mandatory for short options as well. +.TP +\fB\-h\fR, \fB\-\-help\fR +print out the usage message then exit. +.TP +\fB\-n\fR, \fB\-\-number\fR=\fINUM\fR +performs TEST UNIT READY \fINUM\fR times. If not given defaults to 1. +These suffix multipliers are permitted: c C *1; w W *2; b B *512; +k K KiB *1,024; KB *1,000; m M MiB *1,048,576; MB *1,000,000; +g G GiB *1,073,741,824; and GB *1,000,000,000 . Also a suffix of the +form "x<n>" multiplies the leading number by <n>. Alternatively a hex +number may be given, prefixed by either '0x' or has a trailing 'h'. +.TP +\fB\-O\fR, \fB\-\-old\fR +switch to older style options. +.TP +\fB\-p\fR, \fB\-\-progress\fR +show progress indication (a percentage) if available. If \fI\-\-number=NUM\fR +is given and \fINUM\fR is greater than 1 then waits 30 seconds before +subsequent checks. Exits when \fINUM\fR is reached or there is no more +progress indication. Ignores \fI\-\-time\fR option. +.TP +\fB\-t\fR, \fB\-\-time\fR +after completing the requested number of TEST UNIT READY commands, outputs +the total duration and the average number of commands executed per second. +.TP +\fB\-v\fR, \fB\-\-verbose\fR +increase level or verbosity. +.TP +\fB\-V\fR, \fB\-\-version\fR +print version string then exit. +.SH EXIT STATUS +The exit status of sg_turs is 0 when it is successful. Otherwise see +the sg3_utils(8) man page. +.SH OLDER COMMAND LINE OPTIONS +The options in this section were the only ones available prior to sg3_utils +version 1.23 . In sg3_utils version 1.23 and later these older options can +be selected by either setting the SG3_UTILS_OLD_OPTS environment variable +or using '\-\-old' (or '\-O) as the first option. +.TP +\fB\-n\fR=\fINUM\fR +performs TEST UNIT READY \fINUM\fR times. If not given defaults to 1. +Equivalent to \fI\-\-number=NUM\fR in the main description. +.TP +\fB\-N\fR +switch to the newer style options. +.TP +\fB\-p\fR +show progress indication (a percentage) if available. +Equivalent to \fI\-\-progress\fR in the main description. +.TP +\fB\-t\fR +after completing the requested number of TEST UNIT READY commands, outputs +the total duration and the average number of commands executed per second. +Equivalent to \fI\-\-time\fR in the main description. +.TP +\fB\-v\fR +increase level of verbosity. +.TP +\fB\-V\fR +print out version string then exit. +.SH AUTHORS +Written by D.
