* exec foreman to replace current process Use `exec` to invoke `foreman` to make sure `bin/dev` is replaced by the `foreman` process. This ensures that `foreman` gets `bin/dev`'s pid (so it's cleaned up properly) and that interrupts and signals (like `ctrl+c`) are handled correctly by `foreman` (to shut down child processes). * Use sh as least common denominator shell Some distros don't ship with bash, but will have sh. see also: rails/cssbundling-rails#98

This fixes a couple issues we ran into, using small alpine ruby image under docker, developing locally with docker compose:
use
execto invokeforeman. This ensures thedevscript is replaced by theforemanprocess and signals/interrupts like ctrl+c are handled correctly. Without this, the childforemanprocesses are not stopped gracefully and the PID file not cleaned up.replace
bashwithsh. Alpine Linux (for example) ships withash(notbash) but includessh, so this seems like a reasonable choice as "lowest common denominator"Gist of minimal test case:
