I disagree with Chet on that. My assessment is that POSIX/SUS is ambiguous on this. It is true that only simple commands can lead to the shell exiting. However, it also explicitly excludes pipelines starting with !. This can be construed as indicating that simple commands that are a part of a pipeline not preceded with ! can cause an exit. Of course dash's current interpretation only includes the last component of the pipeline, when not preceded by !. > Since I like dash behavior more (makes it easier to write reliable > scripts), I'm considering switching my program (cruft) to dash.

I make no guarantees on this as SUS is subject to revision. However, I also have no plans to change this until such SUS clarifies this which probably won't occur for eons.
