Multiple commands in build.command fail on Linux

[tcmal]

For example, with a rust project:

[build]
command = "cargo install -q worker-build && worker-build --release" # required

I get:

$ wrangler dev -l build/worker/shim.mjs
running: cargo install -q worker-build && worker-build --release
╭───────────────────────────────────────────────────────────────────────────────────────────────────────────────────╮
│ B to open a browser, D to open Devtools, S to turn on (experimental) sharing, L to turn off local mode, X to exit │
╰───────────────────────────────────────────────────────────────────────────────────────────────────────────────────╯
error: Found argument '--release' which wasn't expected, or isn't valid in this context

USAGE:
...

Indicating cargo is being passed worker-build --release as an argument.

I think this is caused here, and it should be something like execva('sh', ['-c', commandPieces.join(" ")])

This looks like it would also affect mac and windows, though I can't test either.

Using v0.0.7 with node v16.13.1

Great catch. Will fix.
