+You shouldn't. See (info "(bash)Redirections") :\r
+\r
+ #+begin_quote\r
+ Bash handles several filenames specially when they are used in\r
+ redirections, as described in the following table:\r
+\r
+ [...]\r
+ `/dev/tcp/HOST/PORT'\r
+ If HOST is a valid hostname or Internet address, and PORT is an\r
+ integer port number or service name, Bash attempts to open a TCP\r
+ connection to the corresponding socket.\r
