While I get it to work in the GUI, running the beginners tutorial through a Linux terminal gives me the following output:

```
Attached property Antisymmetric to F_{µ ν}.
Attached property Accent to δ{#}.
- 1/4 ∫(F^{µ ν}F_{µ ν}}{x}
F_{µ ν} = \partial_{µ}(A_{ν}) - \partial_{ν}(A_{µ})
F_{µ ν} = \partial_{µ}(A_{ν}) - \partial_{ν}(A_{µ})
F_{µ ν} = \partial_{µ}(A_{ν}) - \partial_{ν}(A_{µ})
F_{µ ν} = \partial_{µ}(A_{ν}) - \partial_{ν}(A_{µ})
F_{µ ν} = \partial_{µ}(A_{ν}) - \partial_{ν}(A_{µ})
F_{µ ν} = F_{µ ν}
F_{µ ν} = F_{µ ν}
```

So aside from the weird brackets in the integral, it seems like it's completely skipping the definition of the action. Does anyone know what could be causing this?

Also, if I can sneak in a bonus question, is there any documentation on how to run cadabra through a terminal specifically?
