Basic CLI

cmd.js

#!/usr/bin/env node
const { mkdirSync, writeFileSync } = require('node:fs');

const params = process.argv.slice(2);

if (params.length === 0) {
  console.log('No arguments provided');
  process.exit(1);
}

const dir = params[0];

mkdirSync(dir, { recursive: true });

writeFileSync(`${dir}/index.html`, '');

cmd.sh

#!/bin/bash
mkdir $1
cd $1
touch index.html

usage.md

Chose one or the other file according to your preference (Mac/Unix)

• chmod +x <filename> => To make it executable
• ./bash.js foo => will create a repository foo and a file foo/index.html
• ./bash.sh bar => will create a repository bar and a file bar/index.html

Now it will run only in the current directory. If you want to run it globally on your computer

Use a name without extension:

• mv cmd.js cmd or mv cmd.sh cmd
• pwd => to get your current directory.
• export PATH=$PATH:<pwd result>/cmd

Now in this terminal, you can always use your command like:

• cmd baz => will create a repository baz and a file baz/index.html

But it will work only on this terminal, so use:

• Move your cmd file in one of your main directories. e.g: ~/scripts folder
• Open the ~/.bash_profile (depending on your terminal you might need to open one of this other file in the section Set your PATH permanently)
• Add to the line export PATH (if not already there): export PATH=$PATH:/Users/<username>/scripts/cmd
