Solo-rb

A ruby port of 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.

Add this line to your application's Gemfile:

gem 'solo-rb'

And then execute:

$ bundle

Or install it yourself as:

$ gem install solo-rb

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

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.
