Scripts

A collection of my bash and python scripts.
Work in progress; I'm planning to add more scripts as I think of tasks to simplify!

Getting Started

1. Setting up the environment

I write and use these scripts in a Linux environment (WSL 2 Ubuntu 20.04). I expect them to work on MacOS too. For Windows users, I highly suggest setting up the Windows Subsystem for Linux.

2. Python

For the Python scripts, I recommend installing Python 3.6+ (comes with pip too), since I often use f-strings. Miniconda3 environments are really easy to manage.

Usage

If you try using any of these, remember to give execute permissions to the script.

$ chmod +x script_name

This will allow you to run the scripts as shown:

$ ./script_name

Tip: Add the scripts directory to your $PATH by including the line below to your shell configs to access them from anywhere!

$ export PATH="/path/to/scripts:$PATH"

Then, you can use the script like this from any working directory:

$ google "youtube the best of the beatles"

Please refer to the individual scripts for detailed usage information.
