You can also use it in cases where a program doesn't take input from stdin as in the above. Think of it as the same things as using the pipe character "|" but output goes to a file and input is read from the file. It's also useful in cases where you need to periodically retrieve data but don't want a huge program sitting around in memory listening to a regular pipe. >From a google search: http://whatis.techtarget.com/definition/0,,sid9_gci212619,00.html named pipe In computer programming, a named pipe is a method for passing information from one computer process to other processes using a pipe or message holding place that is given a specific name. Unlike a regular pipe, a named pipe can be used by processes that do not have to share a common process origin and the message sent to the named pipe can be read by any authorized process that knows the name of the named pipe. A named pipe is sometimes called a "FIFO" (first in, first out) because the first data written to the pipe is the first data that is read from it.
