       This  bash  shell  script calls the sg_turs utility on each given DEVICE. This will send a SCSI TEST UNIT
       READY command to each DEVICE. Disks, tape drives and DVD/BD players amongst others may  respond  to  this
       SCSI command.

       The exit status of this script is 0 when it is successful. Otherwise the exit status is that of the  last
       sg_turs utility called. See the sg3_utils(8) man page.
