# Custom CLI Script

A custom CLI script is a function to execute through Medusa's CLI tool. This is useful when creating custom Medusa tooling to run as a CLI tool.

## How to Create a Custom CLI Script?

To create a custom CLI script, create a TypeScript or JavaScript file under the `src/scripts` directory. The file must default export a function.

For example, create the file `src/scripts/my-script.ts` with the following content:

```ts title="src/scripts/my-script.ts"
import { 
  ExecArgs,
  IProductModuleService
} from "@medusajs/types"
import { ModuleRegistrationName } from "@medusajs/modules-sdk"

export default async function myScript ({
  container
}: ExecArgs) {
  const productModuleService: IProductModuleService = 
    container.resolve(ModuleRegistrationName.PRODUCT)

  const [, count] = await productModuleService.listAndCount()

  console.log(`You have ${count} product(s)`)
}
```

The function receives as a parameter an object having a `container` property, which is an instance of the Medusa Container. Use it to resolve resources in your Medusa application.

## How to Run Custom CLI Script?

To run the custom CLI script, `build` your code then run the `exec` command:

```bash
npm run build
npx medusa exec ./dist/scripts/my-script.js
```

Notice that you pass the path to the file in the `dist` directory.

## Custom CLI Script Arguments

Your script can accept arguments from the command line. Arguments are passed to the function's object parameter in the `args` property.

For example:

```ts
import { ExecArgs } from "@medusajs/types"

export default async function myScript ({
  args
}: ExecArgs) {
  console.log(`The arguments you passed: ${args}`)
}
```

Then, pass the arguments in the `exec` command after the file path:

```bash
npm run build
npx medusa exec ./dist/scripts/my-script.js arg1 arg2
```
