#46 # Node version (or tell us if you're using electron or some other framework):
Node 14.10
React ^16.11.00
react-scripts 3.4.1

ShellJS version (the most recent version/Github branch you see the bug on):

^0.8.4

Operating system:

OS X 10.15.6

Description of the bug:

I want to execute a simple print command using standard input from inside a React app.
If this is not possible, it would be great to receive feedback on how to do this!
For example, perhaps I can setup a local node server that deploys with the react app and embed shelljs into the node server instead.

Example ShellJS command to reproduce the error:

import React from 'react';
[...]
import shell from 'shelljs';
shell.config.execPath = 'v14.1.0';

[...]
shell.exec(`echo "some text" | lp`);
[...]
