Hi,
scsiinfo:
>>> Eric Youngdale ** - 11/1/93. Version 1.0.
Version 1.81 was ported to sginfo in 1998 and placed in the
sg_utils package. For more than 10 years I have been trying
to discourage people from using it. It contains next to no
modern VPD or mode pages and many of the standard INQUIRY
response fields it lists are now obsolete.
Curious about what sginfo and sysfs have in common. Oh well,
looks like I have my first patch for sg3_utils version 1.39 .

sginfo <device> prints out various fields such as Vendor and Product in
INQUIRY response with spaces (0x20) characters.
This can confuse scripts some users have.
A change to sysfs attributes such that it now includes spaces caused
this problem.
Strip out those trailing spaces (if any).
