OCR and Audio Transcription Script

This script performs Optical Character Recognition (OCR) on images within a specified folder and extracts and transcribes audio from a video file. The extracted text from images and the transcription from the audio are saved in separate output text files.

Features

OCR from Images: Extracts text from all image files in a specified folder (frames) and saves it to knowledge2.txt one directory level up.
Audio Transcription: Extracts audio from a specified video file (input.mkv), transcribes it using the Whisper model, and saves the transcription to a text file named input-transcription.txt.

Adding nushell as default shell

If you try to add nushell as your default terminal with chsk, you'll encounter an error because nushell isn't added to the /etc/shells list by default. To add it to the whitelist, append your nu binary file to etc/shells

echo 'usr/bin/nu' | sudo tee -a /etc/shells

After it is added, you can set it as default shell with

chsh -s (which nu)

I compiled a list of useful tweaks I usually use while configuring my freshly installed distro.

Everything in this guide is made of Ubuntu/Debian based systems in mind, so it might not function the same on different package managers and distros
