Nano is a text editor available in [[Bash]]. Use nano to explore file contents and make changes if needed. When developing in a cloud environment, you may need nano to read and edit files when an [[IDE]] is not available. An alternative to nano is [[vim]].
To open a file in nano, type
```bash
nano <filename>
```
Make changes and then save with `Ctrl+O` and exit with `Ctrl+X`.
