Arguments for Node child_process "spawn()"

Using child_process (spawn) to open a new BASH terminal and execute the commands in each file.

I want to add all of my .sh files, that I'm going to spawn, into a folder to clean up my project directory.

PROBLEM: I can't figure out how to change the directory the scripts run from, and the docs are a little to heavy for me at this point.

SIMPLE TEST EXAMPLE, WITH MY FIRST TWO FILES FOR CONNECTING (each .sh file would be in the project folder):

    const { spawn } = require('node:child_process');

    const bat = spawn('cmd.exe', ['/c', 'connect.sh']);

/*
    <connect.sh> // 1st .sh file
    #!/usr/bin/env bash  //to make it bash
    HTTP_PORT=3002 P2P_PORT=5002 PEERS=ws://localhost:5001 npm run dev

    <connect1.sh> // 2nd .sh file
    #!/usr/bin/env bash   //to make it bash
    HTTP_PORT=3003 P2P_PORT=5003 PEERS=ws://localhost:5002,ws://localhost:5001 npm run dev
*/

I have 9 of these files to connect up to 10 peers. And I would like to put them in a folder to simplify my project structure.

This is my actual API call below.... // Uses length to determine which file to run

     app.post("/peers/connect", async function (req, res) {
      const peerInfo = await peers.info();
      // no peers yet
      if (typeof peerInfo === "string") {
        let bat = spawn("cmd.exe", ["/c", "connect.sh"]);
        res.json("A new terminal has opened! You are now connected!");
      } else { 
        // peers exist
        let length = peerInfo.peers;
        // console.log(length);
        let bat = spawn("cmd.exe", ["/c", `connect${length}.sh`]);
        res.json("A new terminal has opened! You are now connected!");
      }
    });

My file structure here...you can see why I want a folder for these!

My file structure

RECAP: Help my put all of these files into a folder (shellScripts) and have the code still work :) Thanks! (just realized we might have to cd back into project folder before "npm run dev" in each file?)

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
