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:
“Universal empire is the prerogative of a writer. His concerns are with all mankind, and though he cannot command their obedience, he can assign them their duty. The Republic of Letters is more ancient than monarchy, and of far higher character in the world than the vassal court of Britain.”
—Thomas Paine (1737–1809)
“One line typed twenty years ago
can be blazed on a wall in spraypaint
to glorify art as detachment
or torture of those we
did not love but also
did not want to kill.”
—Adrienne Rich (b. 1929)
