A number of key applications have been ported, as have programs used by the system itself, and the requisite libraries from Plan 9. All of these have been made to work on top of a Unix-like environment, rather than their native Plan 9.

A number of key applications have been ported, as have programs used by the system itself, and the requisite libraries from Plan 9. All of these have been made to work on top of a Unix-like environment, rather than their native Plan 9. Some of the most significant ported components are:
- v9fs - a client and server implementation of the 9P
9P is a network protocol developed for the Plan 9 from Bell Labs distributed operating system as the means of connecting the components of a Plan 9 system. Files are key objects in Plan 9. They represent windows, network connections, processes, and almost anything else available in the operating...

rc is the command line interpreter for Version 10 Unix and Plan 9 from Bell Labs operating systems. It resembles the Bourne shell, but its syntax is somewhat simpler. It was created by Tom Duff, who is better known for an unusual C programming language construct called Duff's device.A port of the...

Sam is a structural-regular-expressions-based multi-file text editor. It was originally designed in the early 1980s at Bell Labs by Rob Pike with the help of Ken Thompson and other Unix developers for the Blit windowing terminal running on Unix; it was later ported to other systems. Sam follows a...

Acme is a text editor and graphical shell from the Plan 9 from Bell Labs operating system, designed and implemented by Rob Pike. It can use the sam command language. The design of the interface was influenced by Oberon. It is different from other editing environments in that it acts as a 9P server...

Venti is a network storage system that permanently stores data blocks. A 160-bit SHA-1 hash of the data acts as the address of the data. This enforces a write-once policy since no other data block can be found with the same address...
