When I run
netstat --protocol unix or
lsof -U I see that some unix socket paths are prepended with @ symbol, for example, @/tmp/dbus-qj8V39Yrpa. Then when I run
ls -l /tmp I don't see file named dbus-qj8V39Yrpa there.
The question is what does that prepended @ symbol denote? And second related question, is -- where can I actually find that unix socket file (@/tmp/dbus-qj8V39Yrpa) on the filesystem?
