Pipelines in Command Line Interfaces
All widely used Unix and Windows shells have a special syntax construct for the creation of pipelines. In typical usage one writes the filter commands in sequence, separated by the ASCII vertical bar character "|" (which, for this reason, is often called "pipe character"). The shell starts the processes and arranges for the necessary connections between their standard streams (including some amount of buffer storage).

Famous quotes containing the words command and/or line:
“The Modernist’s command was Pound’s “Make it New.” The postmodern imperative is “Get it Used.” The more used the better.”
—Andrei Codrescu (b. 1946)
“I had crossed de line of which I had so long been dreaming. I was free; but dere was no one to welcome me to de land of freedom. I was a stranger in a strange land, and my home after all was down in de old cabin quarter, wid de ole folks, and my brudders and sisters. But to dis solemn resolution I came; I was free, and dey should be free also; I would make a home for dem in de North, and de Lord helping me, I would bring dem all dere.”
—Harriet Tubman (c. 1820–1913)
