UNIX to Plan 9 translation

What follows is a table of transliterations from UNIX to Plan 9 commands or syntactical elements of Bourne-like shells to the Plan 9 rc shell.

Plan 9 commands are typically not direct ports of UNIX commands and as such should not be expected to operate the same.

When in doubt, UNIX refers to your average GNU/Linux distribution and a Bourne-like shell, most likely bash(1). Similarly, when in doubt, Plan 9 refers to the 9front fork of Plan 9.
