In computing, a named pipe (also known as a FIFO for its behavior) is an extension to the traditional pipe concept on Unix and Unix-like systems, and is one of the methods of inter-process communication. The concept is also found in Microsoft Windows, although the semantics differ substantially. A traditional pipe is "unnamed" because it exists anonymously and persists only for as long as the process is running. A named pipe is system-persistent and exists beyond the life of the process and must be deleted once it is no longer being used. Processes generally attach to the named pipes (usually appearing as a file) to perform inter-process communication (IPC).

Famous quotes containing the words named and/or pipe:
“We were hospitably entertained in Concord, New Hampshire, which we persisted in calling New Concord, as we had been wont, to distinguish it from our native town, from which we had been told that it was named and in part originally settled. This would have been the proper place to conclude our voyage, uniting Concord with Concord by these meandering rivers, but our boat was moored some miles below its port.”
—Henry David Thoreau (1817–1862)
“On a cloud I saw a child,
And he laughing said to me,
“Pipe a song about a Lamb”;
So I piped with merry chear.
“Piper pipe that song again”—
So I piped, he wept to hear.
“Drop thy pipe thy happy pipe
Sing thy songs of happy chear”;
So I sung the same again
While he wept with joy to hear.”
—William Blake (1757–1827)
