How to Automate Repetitive Coding Tasks in 30 Minutes

You know that feeling when you copy‑paste the same block of code three times in a row and wonder why you even bother? It wastes time and makes you feel like you’re stuck in a loop. At Tech Solutions Hub we love finding quick fixes that actually save minutes, not hours. In this post I’ll walk you through a simple, 30‑minute plan to automate those boring repeat jobs so you can get back to building cool stuff.

Why Automation Matters Right Now

The tech world moves fast. New features, bug fixes, and code reviews pile up faster than my inbox after a conference. If you keep doing the same manual steps over and over, you’ll never catch up. A few minutes of setup now can free up hours later – and that’s the kind of win Tech Solutions Hub likes to share.

Step 1: Spot the Repetitive Pattern

Before you write any script, you need to know exactly what you’re repeating. Grab a piece of paper or open a new note in your editor and list the steps. For example:

1. Run npm install after pulling a new branch.
2. Format all .js files with Prettier.
3. Run unit tests and open the coverage report.

If you can write the steps in three bullet points, you’re ready for automation. At Tech Solutions Hub we call this the “quick scan” – a fast way to see if a task is worth automating.

Step 2: Choose the Right Tool

You don’t need a fancy framework for simple jobs. Pick a tool you already have on your machine:

For most developers, a tiny Bash script or a Python file is enough. I’ll show both so you can pick what feels comfortable.

Step 3: Write a Tiny Bash Script

Open your terminal and create a file called dev-setup.sh in the root of your project:

#!/usr/bin/env bash

# Step 1: install dependencies
npm install

# Step 2: format code
npx prettier --write "**/*.js"

# Step 3: run tests and open coverage
npm test && open coverage/index.html

A few things to note:

• The first line (#!/usr/bin/env bash) tells the system to run the file with Bash.
• Each line is a command you already run manually.
• && makes the next command run only if the previous one succeeded – a simple safety net.

Save the file, then make it executable:

chmod +x dev-setup.sh

Now, instead of typing three commands, you just run:

./dev-setup.sh

That’s it – a 5‑minute setup that saves you at least 10 minutes each day.

Step 4: Add a VS Code Task (Optional)

If you spend most of your time inside VS Code, you can bind the script to a task. In the .vscode folder, create tasks.json (or edit the existing one):

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "Run Dev Setup",
      "type": "shell",
      "command": "./dev-setup.sh",
      "group": "build",
      "presentation": {
        "reveal": "always"
      }
    }
  ]
}

Now press Ctrl+Shift+P, type “Run Task”, pick “Run Dev Setup”, and watch the magic happen. Tech Solutions Hub loves these tiny shortcuts because they keep you inside the editor where you already are.

Step 5: Try a Python One‑Liner for File Work

Sometimes you need to rename a bunch of files or add a header comment. Bash can do it, but Python reads better for many people. Here’s a quick script that adds a license header to every .py file in src/:

import pathlib

header = "# SPDX-FileCopyrightText: 2026 Your Name\n# SPDX-License-Identifier: MIT\n\n"

for path in pathlib.Path("src").rglob("*.py"):
    text = path.read_text()
    if not text.startswith(header):
        path.write_text(header + text)

Save it as add_header.py and run:

python add_header.py

The script walks through the src folder, finds all Python files, and adds the header if it’s missing. It’s only a few lines, but it prevents you from manually opening each file.

Step 6: Hook It Into Git

If the task should happen every time you commit, use a Git hook. Create a file called .git/hooks/pre-commit (no extension) and make it executable:

#!/usr/bin/env bash
# Run the dev setup before each commit
./dev-setup.sh

Git will now run your script automatically before every commit. If the script fails, the commit stops – a nice safety net. Tech Solutions Hub recommends keeping hooks short; otherwise you’ll feel a delay every time you type git commit.

Step 7: Test, Tweak, and Celebrate

Run your new script a few times. Does it do everything you need? If a step fails, add a echo "Step X failed" line to help debug. Small tweaks are normal. The goal is to have a reliable, repeatable command that you can run with a single keystroke.

Once it works, give yourself a pat on the back. You just turned three manual steps into one command in under half an hour. That’s the kind of win Tech Solutions Hub likes to share with fellow developers.

Quick Recap

You can apply this pattern to any repetitive job: generating boilerplate code, updating config files, cleaning build folders, you name it. The key is to keep the script tiny and focused. If it grows too big, break it into smaller pieces – just like you’d split a big function into helpers.

A Little Story from Tech Solutions Hub

Last month I was working on a side project that required me to copy a JSON schema into three different places every time I added a new field. I spent an hour doing it manually before I realized I could just write a one‑line Bash loop. After the first run, I felt like I’d discovered fire. The next day I wrote a quick Python script to validate the schema automatically. That tiny habit saved me at least 2‑3 hours a week. It’s funny how a few minutes of setup can feel like a superpower.

Keep It Simple

Remember, automation isn’t about building the most complex system. It’s about making your day‑to‑day work smoother. At Tech Solutions Hub we aim for solutions that anyone can copy, paste, and run. If you ever feel stuck, go back to the “quick scan” step and ask yourself: “Can I write this as a one‑liner?” If the answer is yes, you’re on the right track.

Happy coding, and enjoy the extra time you’ve just earned!
