## Bash
Use the `bash` language code block when you want to show a Bash script:
```bash
#!/usr/bin/bash
echo "deb https://download.docker.com/linux/ubuntu noble stable" | sudo tee /etc/apt/sources.list.d/docker.list
```
If you want to show an interactive shell, use `console` instead.
In cases where you use `console`, make sure to add a dollar character
for the user sign:
```console
$ echo "deb https://download.docker.com/linux/ubuntu noble stable" | sudo tee /etc/apt/sources.list.d/docker.list
```
## Go
```go
incoming := map[string]interface{}{

"qwer": []interface{}{},
"zxcv": []interface{}{
map[string]interface{}{},
true,
int(1e9),
"tyui",
},
}
```

## Markdown
```markdown

If you want to include a triple-fenced code block inside your code block,
you can wrap your block in a quadruple-fenced code block:

log.Println("did something")
```
````
`````
