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").
/A Append the pipeline content to the output file(s) rather than overwriting them. Note: When tee is used with a pipe, the output of the previous command is written to a temporary file. When that command finishes, tee reads the temporary file, displays the output, and writes it to the file(s) given as command-line argument.
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.
