MPW Shell

MPW Shell is a re-implementation of the Macintosh Programmer's Workshop shell. The primary reason is to support MPW Make (which generated shell script). It may also be useful for other things.

Supported features

  • If ... [Else If] ... [Else] ... End
  • Begin ... End
  • Loop ... End
  • For name In [word...] ... End
  • Break [If], Continue [If]
  • ( ... )
  • ||
  • &&
  • redirection
  • | "pipes" (via a temporary file. Presumably, that's what MPW did as well.)

Not (yet) supported

  • subshells (..., ...)
  • aliases
  • regular expressions
  • text-editing commands (search forward/backward, et cetera)

Builtin Commands

  • AboutBox
  • Alias
  • Catenate
  • Directory
  • Echo
  • Evaluate
  • Exists
  • Export
  • Parameters
  • Quote
  • Set
  • Shift
  • Unalias
  • Unexport
  • Unset
  • Version
  • Which

Setup

  1. Install MPW. The mpw binary should be somewhere in your $PATH. It also checks /usr/local/bin/mpw and $HOME/mpw/bin/mpw
  2. Copy the Startup script to $HOME/mpw/. This script is executed when mpw-shell (or mpw-make) starts up (imagine that) and should be used to set environment variables.
