plumbing n.
[Unix] Term used for shell code,
so called because of the prevalence of `pipelines' that feed the
output of one program to the input of another. Under Unix, user
utilities can often be implemented or at least prototyped by a
suitable collection of pipelines and temp-file grinding
encapsulated in a shell script; this is much less effort than
writing C every time, and the capability is considered one of
Unix's major winning features. A few other OSs such as IBM's
VM/CMS support similar facilities. Esp. used in the construction
`hairy plumbing' (see hairy). "You
can kluge together a basic spell-checker out of
sort(1), comm(1), and
tr(1) with a little plumbing." See also tee.
