|

because of the prevalence of <span class="firstterm">pipelines</span> 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 <span class="firstterm">hairy plumbing</span> (see
