# Capistrano::RunningProcessCheck

This gem checks running process names before all Capistrano tasks, to prevent the process effects deployment.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'capistrano-running_process_check'
```

And then execute:

    $ bundle install

Or install it yourself as:

    $ gem install capistrano-running_process_check

## Usage


Add line below to `Capifile`.

```ruby
require "capistrano/running_process_check"
```

Please append process names to disallow running while deployment.

```ruby
append :disallowed_running_processes, /foo/, "bar"
```

When you run `cap` command (with stage name), checks running process. And if it is running, prints message below and abort deployment.

        ================================================================================
        !!! Some /foo/ process(es) are running. Please kill them. !!!
        ================================================================================
