View source for List of Plan 9 applications

{{Short description|none}}
This is a '''list of [[Plan 9 from Bell Labs|Plan 9]] [[Computer program|program]]s'''. Many of these programs are very similar to the [[List of Unix commands|UNIX programs]] with the same name, others are to be found only on [[Plan 9 from Bell Labs|Plan 9]]. Others again share only the name, but have a different behaviour.
