3. Testing and debugging: When developing Elvish scripts, you can use the "elvish" command to test and debug the scripts interactively, facilitating iterative development.

Overall, the "elvish" command enables you to work with the Elvish programming language, providing a user-friendly environment to write scripts, run them, and perform various tasks in a Unix-like command-line interface.
