sg_turs - executes a user specified number of TEST UNIT READY commands on the given device

sg_turs [-n=<number of commands to send>] [-t] [-v] [-V] <scsi_device>

sg_turs sends a number of TEST UNIT READY commands to a given SCSI device. 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.

-n=<num>

performs TEST UNIT READY "<num>" 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 0X.

-t

after completing the requested number of TEST UNIT READY commands, outputs the total duration and the average number of commands executed per second.

-v

increase level of verbosity: print out SCSI commands in hex prior to sending them to the device. '-vv' and '-vvv' are also accepted yielding greater verbosity.

-V

print out version string then exit.
