# Program alias

A name such as production that points at one version of a program and can be moved without changing the code that runs it.

Jobs and schedules run acme-report@production; you test version 4, then move production to it. A bad release is rolled back by moving the alias back.

```
kaab programs alias set acme-report production 4
```
