<!-- Section from "doc/guides/02.Usage.md.hbs" Start -->

<a name="section-doc-guides-02-usage-md"></a>

Usage
---------

Step01: Create script file to run. File basename will be the subject id

**/home/scripts/v/jp.realglobe.v-daemon.example01**

```javascript
#!/usr/bin/env node

/**
 * @file Example script to daemonize
 */
'use strict'

// verb and object passed as process args
const [, , subject, verb, object1, object2] = process.argv

switch (verb) {
  case 'sayHi': {
    process.stdout.write(`Hi, ${object1} and ${object2}`)
    break
  }
  default:
    throw new Error(`Unknown verb: ${verb}`)
}
```


Step02: Daemonize the script

```bash
#!/bin/bash

# Give script path to daemonize

v-daemon /home/scripts/v/jp.realglobe.v-daemon.example01 -H "v-spot.cloud.com"
```

Step03: Call it from another client
```javascript
#!/usr/bin/env node

/**
 * Example to call daemonized script
 */
'use strict'

const vSpot = require('v-spot')

;(async () => {
  const spot = vSpot().client()

  await spot.connect('v-spot.cloud.com')

  // By default, subject name is generated from script name
  const example01 = await spot.use('jp.realglobe.v-daemon.example01')
  // Send the signal to daemon script via server
  await example01.sayHi('can you hear me?', 'really?')
})()

```


### More Script Examples

**Bash Script Example**
```bash
#!/bin/bash
#

subject=$1
verb=$2
object1=$3
object2=$4

if [[ ${verb} == *"sayHi"* ]]
then
  printf "Hi, ${object1} and ${object2}"
  exit
fi

echo "Unknown verb ${verb}"
exit 1
```
