Glad that "utuser -p" is on the right lines at least :)
But there's no real lightweight way to get the DTU token ? I need to be
able to disable speaker output if a session is migrated to a DTU in,
say, a library for example.
I don't think we realized how common this request might be.
If you have the latest 4.1 (or 4.0) patch, try utuser -xo. It's similar
to utuser -o, but includes the logical token as the first field.
It's not documented, which should probably be corrected, since clearly
it has value to some users.
utuser -xo is somewhat more expensive than utuser -p, because it has to
read and format records for all the tokens instead of just one, but it's
friendlier to parse and the difference in cost shouldn't be that great.
It's nowhere near as expensive as something involving a utauthd callback
- I wouldn't worry about it.
It's prettier, but I still need to run it through awk and I still don't
get the DTU id from it. Does "utsession -l -t foo.wibble" do a utauthd
callback?
I believe the cheapest way to get the DTU id is to resolve the
$DTDEVROOT/unit symlink.
