# In a [CPU] the next instruction might be being decoded while the current one is being executed, that's a PipeLine. |

|

# In a CommandLine the second command might start processing the output of the first command before the first command has terminated, that's also a PipeLine. |

There is a nifty little program called "pipe viewer" (debian/ubuntu - install "pv") |

Eg, instead of ''grep pattern hugefile'', you can ''pv hugefile | grep pattern''. You can also insert it into the middle of a pipeline and give it options telling it the length of stdin, and if it can't work out the length it can give you statistics such as how fast the data is being processed. Neat. |
