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

SYNOPSIS
sg_turs [-n=<number of commands to send>] [-t] <generic device>

DESCRIPTION

sg_turs sends a number of TEST UNIT READY commands to a given SCSI generic 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. Postfix multipliers "k" (1024), "K" (1000), "m" (1048576) or "M" (1000000) may be applied to "<num>". 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.
