Currently it does the account but does not delete the "/".

```auto
ruby {
    		code => '
        		event.set("execution_length_input", event.get("[execution][input]").to_s.length - 
                        ("[execution][input]").to_s.count("\") )
			'
		}

```

You could try

```
        code => '
            e = event.get("[execution][input]")
            if e
                event.set("execution_length_input", e.to_s.delete("/").length)
            end
        '
```
