# Solo-rb

A ruby port of [Solo](https://www.timkay.com/solo/). Solo-rb is a pretty simple gem that prevents a program from running more than one copy at a time. It is useful with cron to make sure that a job doesn't run before a previous one has finished.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'solo-rb'
```

And then execute:

$ bundle

Or install it yourself as:

$ gem install solo-rb

## Usage

solo --port=PORT -- COMMAND

where
PORT a port number to be used for locking. Must be less than 65535 and ports under 1024 are reserved for root
COMMAND shell command to run

options
--silent be silent

## Development

To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
