# exec

> Run a script with the Base44 SDK pre-authenticated

Run a TypeScript or JavaScript script with the Base44 SDK pre-authenticated as the current user. The SDK is available as a global `base44` variable. Scripts are executed locally using Deno.

For a full walkthrough, use cases, and prerequisites, see the [Standalone scripts](/developers/backend/overview/run-scripts) guide.

## Usage

Pipe a script file to exec:

```bash theme={null}
cat ./script.ts | base44 exec
```

Or pass inline code:

```bash theme={null}
echo "console.log(await base44.entities.Tasks.list())" | base44 exec
```
