Bash
In plain terms
The default command-line shell and scripting language on Unix-like systems.
Going deeper
Bash runs commands interactively and in scripts to automate tasks, glue tools together, and manage systems. It's everywhere on Linux and macOS.
Under the hood
Powerful for pipelines and automation but error-prone for complex logic; quoting and edge cases trip people up, so heavy logic moves to Python.
Examples
Deployment scripts, cron jobs, CI pipelines, server administration, dotfiles.
Think of it like...
Like the duct tape and string of computing: it connects everything together quickly.
