The article explores using text editors as lightweight user interfaces for command-line tools, leveraging the $EDITOR environment variable to avoid building custom TUIs. It provides examples like crontab -e and git commit, along with a simple script demonstrating how programs can delegate editing tasks to users' preferred editors. This approach offers familiar editing capabilities without the development overhead of custom interfaces.
