A pipeline of three program processes run on a text terminal In Unix-like computer operating systems , a pipeline is a mechanism for inter-process communication using message passing. A pipeline is a set of processes chained together by their standard streams , so that the output text of each process ( stdout ) is passed directly as input ...

A pipeline of three programs run on a text terminal Programs can be run together such that one program reads the output from another with no need for an explicit intermediate file. command1 | command2 executes command1 , using its output as the input for command2 (commonly called piping , with the " | " character being known as the "pipe").
PowerShell – An object-oriented shell developed originally for Windows OS and now available to macOS and Linux. Qshell – A shell on the IBM i operating system based on POSIX and X/Open standards. rc – The default shell on Plan 9 from Bell Labs and Version 10 Unix written by Tom Duff. Ports have been made to various Unix-like operating ...
Instead of a conventional, unnamed, shell pipeline, a named pipeline makes use of the filesystem.It is explicitly created using mkfifo() [1] or mknod(), [2] and two separate processes can access the pipe by name — one process can open it as a reader, and the other as a writer.
Most tasks [a] (directory listing, editing files, etc.) can easily be accomplished by letting the program take control of the terminal and returning control to the shell when the program exits – formally, by attaching to standard input and standard output to the shell, which reads or writes from the terminal, and catching signals sent from ...
In computing, process substitution is a form of inter-process communication that allows the input or output of a command to appear as a file. The command is substituted in-line, where a file name would normally occur, by the command shell.
In computing, a pipeline or data pipeline [1] is a set of data processing elements connected in series, where the output of one element is the input of the next one. The elements of a pipeline are often executed in parallel or in time-sliced fashion. Some amount of buffer storage is often inserted between elements. Computer-related pipelines ...
