# Advanced configuration

MiGA allows flexible execution using a number of techniques, mainly setting [project metadata flags](/part5/metadata.md#project-flags), [dataset metadata flags](/part5/metadata.md#dataset-flags), and through the [daemon configuration](/part4/daemons.md).

These are some examples of advanced behaviors that can be configured in MiGA

## Controlling many daemons at once

The [MiGA CLI](https://github.com/bio-miga/miga/tree/7d5b5d8ca7b592d2dd8e085f33813de3ea42030a/manual/part3/miga-cli.md) includes support for mass-controlled daemons when several MiGA projects are in the same folder using the `miga lair` command.

The MiGA Lair will find all the MiGA projects in a folder (or subfolders) and control all the corresponding daemons together:

```bash
# Check the current status of all the daemons
miga lair list -p /path/to/folder

# Terminate all the daemons at once
miga lair terminate -p /path/to/folder

# Launch and daemonize a process to keep all daemons running
miga lair start -p /path/to/folder

# See more options
miga lair -h
```

## Sending an email when the project is ready

If your project runs for a long time and you want to be notified by email when it's ready, you can use [project hooks](/part5/metadata.md#project-hooks):

```bash
# First cd to the project folder
cd /path/to/project

# And open the MiGA Console
miga c
```

In the MiGA Console:

```ruby
# Set the hook "on_preprocessing_ready" to
# execute a shell command ("run_cmd") consisting of
# sending an email with the project path ("{{project}}")
MiGA::Project.load('.').tap do |p|
  p.metadata[:on_preprocessing_ready] = [
    ['run_cmd', 'echo \'Project ready: {{project}}\' | sendmail me@example.com']
  ]
end.save
quit
```

Make sure to change `/path/to/project` to the project path and `me@example.com` to the email where you want to receive the notification. Also, note that depending on your `sendmail` configuration you might get that email in the spam folder (or flat-out rejected), so make sure to test `sendmail` first.
