When pub creates executable script, it doesn't work on Linux Mint / Ubuntu due to use of sh

For example, the following script generated for csp_fixer fails to run on linux mint, as 'sh' is really dash, and a really restricted shell

!/usr/bin/env sh

This file was created by pub v1.8.5.

Package: csp_fixer

Version: 0.1.3

Executable: csp_fixer

Script: csp_fixer

dart "/home/daniel/.pub-cache/global_packages/csp_fixer/bin/csp_fixer.dart.snapshot" "$@"

csp_fixer some/path

fails with "dart not found"

but bash has PATH properly set up, and dart can be run from the shell prompt

PATH is not being forwarded to sh, or sh on Mint ( which is supplied by dash ) doesn't properly support it.

Some method should be provided to change the shell used, or perhaps a more universal option found.

I suspect you have your PATH configured improperly; I can't imagine that it wouldn't respect PATH, since not only is it part of the spec, it's crucial to executing anything ever. When we fixed issue #1211, we ran the "checkbashisms" script to be sure we weren't accidentally doing anything wrong, and it came up clean, indicating that we weren't relying on any bash-specific in these scripts anymore.

Path is set fine. The problem is SH under Ubuntu is DASH, and the generated script has bashisms that Dash doesn't support.

The biggest I suspect is this:

dash doesn't expand ~ on path search

Given how many people use ~ in their PATH when referring to local installs.

That does sound like PATH is set incorrectly. If you want to use Dash as your default shell, you shouldn't put Dash-incompatible stuff in the environment variables it reads.
