sg3_utils is a package of command line utilities for sending SCSI commands
to storage devices. It some contexts it can send ATA and NVMe commands.
The package targets the Linux 5, 4, 3, 2.6 and 2.4 kernel series. It has
ports to FreeBSD, Android, Solaris, and Windows (cygwin and MinGW).
For an overview of sg3_utils and downloads see this page:

The sg_ses utility (for enclosure devices) is discussed at:

....
Wow, almost 18 months since the last release. Will try to bring that back
to roughly six months.

PS My subversion revision at the release point was 843, but the github mirror
may show revision 844. That last revision is the release tag.
