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:
“I at least have so much to do in unravelling certain human lots, and seeing how they were woven and interwoven, that all the light I can command must be concentrated on this particular web, and not dispersed over that tempting range of relevancies called the universe.”
—George Eliot [Mary Ann (or Marian)
“We are apt to say that a foreign policy is successful only when the country, or at any rate the governing class, is united behind it. In reality, every line of policy is repudiated by a section, often by an influential section, of the country concerned. A foreign minister who waited until everyone agreed with him would have no foreign policy at all.”
—A.J.P. (Alan John Percivale)
