How to Build a bash based spellchecker

Misspellings in scripts, documentation, or emails can be frustrating — but with Linux and a little creativity, you can build your own Bash-based spellchecker that works right from the terminal. This project you are going to create a lightweight, customizable tool to check the spelling of any text file or command-line input, all powered by open-source utilities.
At the heart of this spellchecker is the aspell or hunspell command-line tool, which you’ll integrate with Bash scripts to scan files, highlight errors, and suggest corrections. You’ll build features like:
• Scanning .txt, .md, .html, or code comments
• Ignoring code syntax and custom word lists
• Output formatting with color highlighting or context display
• Interactive correction mode (select replacements or skip words)
• Optional summary reports showing error counts and types
You'll also explore extending your tool with flags for language selection, input filtering, and batch scanning multiple files at once. If you want it to autocorrect typos on the fly or run as a git pre-commit hook? That’s totally possible.
This project is perfect for writers, bloggers, coders, or students who spend a lot of time in the terminal and want to add a smart, efficient quality-control layer to their workflow. Plus, it's a great way to practice Bash scripting, file handling, text processing, and tool integration.
