You typed a 'normal' command (`sleep 60`) and then added in another character,

becomes a *job* in this bash session.

The *job* has two identifiers, which are immediately reported to you in the terminal.

```html
[1] 39165
```

The first is the *job number*, which in this case is `1`, and the second is the
*process identifier*, in this case `39165`, but this will be different for you.
