[docs] add some guidelines for bash scripting

[signebedi]

There area couple ways to script the CLI using bash. For example, you can automate the process of sending multiple questions to the gptty query command using a bash script. This can be particularly useful if you have a list of questions stored in a file, and you want to process them all at once. For example, let's say you have a file questions.txt with each question on a new line, like below.

What are the key differences between machine learning, deep learning, and artificial intelligence?
How do I choose the best programming language for a specific project or task?

What are the essential principles of good software design and architecture?
How do I get started with natural language processing and text analysis in Python?

What are some important concepts in cybersecurity, and how can I apply them to my projects?
How do I ensure that my machine learning models are fair, ethical, and unbiased?

You can send each question from the questions.txt file to the gptty query command using the following bash one-liner:

xargs -d '\n' -I {} gptty query --question "{}" < questions.txt
