• Subsystem: child_process

What steps will reproduce the bug?

test.js

#!/usr/bin/env node
let spawn = require("child_process").spawn;
function showContent(content) {
  spawn(`cat <<< "${content}" | less -r`, {
    stdio: "inherit", // use the current shell for stdio
    shell: true,
  });
}
showContent("hello");

-rwxr-xr-x  test.js

the function is executable. so ./test.js is ok. while error is produce. error is the following

/bin/sh: 1: Syntax error: redirection unexpected

How often does it reproduce? Is there a required condition?

on my mac OS, it is ok, while in the linux, the error will trigger.

What is the expected behavior?

perform normal

What do you see instead?

Additional information

I dig into the <<< redirection，The default system shell in Ubuntu is dash, not bash. Dash does not have the <<< redirection operator. that could be the problem. while I don't know how to solve it.

Wrong repo, moved.

Try passing { shell: '/bin/bash' }.
