Dash is the [default, `/bin/sh` shell on Ubuntu](https://wiki.ubuntu.com/DashAsBinSh). More specifically, dash version 0.5.8-2.10 and others cannot run these two examples:
```sh ```sh
f(){ local e=$1; } f(){ local e=$1; }
f "1 2" f "1 2"
export g=$(printf '%s' "foo 2") export g=$(printf '%s' "foo 2")
``` ```
