Anonymous pipe: A unidirectional data channel using standard input and output. Data written to the write-end of the pipe is buffered by the operating system until it is read from the read-end of the pipe. Two-way communication between processes can be achieved by using two pipes in opposite "directions". All POSIX systems, Windows Named pipe
devpts is a virtual filesystem directory available in the Linux kernel since version 2.1.93 (April 1998). It is normally mounted at /dev/pts and contains solely devices files which represent slaves to the multiplexing master located at /dev/ptmx which in turn is used to implement terminal emulators (such as X11 xterm ).

Named pipe. In computing, a named pipe (also known as a FIFO for its behavior) is an extension to the traditional pipe concept on Unix and Unix-like systems, and is one of the methods of inter-process communication (IPC). The concept is also found in OS/2 and Microsoft Windows, although the semantics differ substantially.
PTYs are similar to bidirectional pipes. [3]: 1388 Devpts is a Linux kernel virtual file system containing pseudoterminal devices. Linux implementation is based on System V-style terminals (commonly referred as UNIX 98 pseudoterminals) [4] and provides POSIX and the Single Unix Specification API in the form of a posix_openpt() function since ...
Unix domain socket. In client-server computing, a Unix domain socket is a Berkeley socket that allows data to be exchanged between two processes executing on the same Unix or Unix-like host computer. [1] This is similar to an Internet domain socket that allows data to be exchanged between two processes executing on different host computers.
D-Bus (short for "Desktop Bus" [4]) is a message-oriented middleware mechanism that allows communication between multiple processes running concurrently on the same machine. [5] [6] D-Bus was developed as part of the freedesktop.org project, initiated by GNOME developer Havoc Pennington to standardize services provided by Linux desktop environments such as GNOME and KDE.
Tera Term. Tera Term (alternatively TeraTerm) is an open-source, free, software implemented, terminal emulator (communications) program. It emulates different types of computer terminals, from DEC VT100 to DEC VT382. It supports Telnet, SSH 1 & 2 and serial port connections. It also has a built-in macro scripting language (supporting Oniguruma ...
As an example, although DOS allows the "pipe" syntax, it employs this second approach. Thus, suppose some long-running program "Worker" produces various messages as it works, and that a second program, TimeStamp copies each record from stdin to stdout , prefixed by the system's date and time when the record is received.
