Call any program as if it were a Node.js function
npm install nodejs-shThis is a Node.js port of the sh Python library, that allows you to call any program as if it were a function:
``js
const {ifconfig} = require('nodejs-sh')
let output = await ifconfig('eth0').toString()
console.log(output)
`
Output:
`
