/bin/sh: 1: set: Illegal option -o pipefail

Expected Behavior

The example script works correctly.

#!/usr/bin/env zx

await $`ls -1 | wc -l`

let branch = await $`git branch --show-current`
await $`printf ${branch} | wc`

await $`test -f package.json`

Actual Behavior

The example script doen't work.

$ ./test.mjs 
$ ls -1 | wc -l  # Note: This line is zx output.
/bin/sh: 1: set: Illegal option -o pipefail
  at file:///home/hata6502/zx-test/test.mjs:17:8

I think this error is occured by using sh instead of bash.
set -euo pipefail; seems not work in sh.

$ bash
$ set -euo pipefail; echo "test"
test
$ sh
$ set -euo pipefail; echo "test"
sh: 1: set: Illegal option -o pipefail

Steps to Reproduce the Problem

1. Make test.mjs.
2. Run chmod +x test.mjs
3. Run ./test.mjs

Specifications

• Version: 1.1.0
• Platform:
  • OS: Ubuntu 20.04

I see. Is there and same option as pipefail is sh?
or maybe make this command not fatal.

[hata6502]

Sorry! I resolved.

Resolution
Insert $.shell = '/bin/bash' in the top of script file.
