Or you can think it as a abstract name. It doesn't really exist on the
filesystem. So you can't use cat to access this file. It can only be
read/written by bash. Like this:
$ less < /dev/tcp/localhost/80
It surely exists on other system, but Debian bash package is compiled
with --disable-net-redirections.
Why is bash configured with --disable-net-redirections?
It can produce completely unexpected results. This kind of
feature should not be part of a shell but a special. tool. And
that tool has existed for years already, it's called netcat.
