Arguments to long options are mandatory for short options as well.

for each DEVICE given output a line containing either ' ready' or ' device not ready'. If DEVICE is not found or there is another serious error then an error message will appear instead.
print out the usage message then exit.
increase level or verbosity.

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.
