I actually stopped using Google a long time ago as they don't give
two people the same resuts for the same search.  Targeting.

Try this one:

https://gpsd.io/ubxtool-examples.html#_sudo_sudont

Or just read the man page.

Except for the POSIC mandated details.

And to focus on the environment is to get lost in one of many details.
sudo is insecure, its man page says so, even Leonard Pottering has gone
off against it.  And sudo does things that violate POSIX, so programs
that expect POSIX, like gpsd, fail in "interesting" ways.

Not may, WILL.  RTFM.

Ah, sorry.  Sadly we rarely get reports back when users fix things.
