Cron Info

A command-line tool that parses a cron string and expands each field to show the times at which it will run.

Installation

There are two ways to install Cron Info, either straight from RubyGems or from the repository.

Installing from RubyGems

gem install cron_info

Installing from repository

Clone the repository:

git clone https://github.com/SebastianCoetzee/cron_info.git

Change into the directory:

cd cron_info

Build the gem:

gem build cron_info.gemspec

Install the gem (replace x with the version number of the gem):

gem install cron_info-x.x.x.gem

Usage

Run the tool with the following command, which parses a cron string and expands each field to show the times at which it will run:

cron_info "*/15" 0 1,15 "*" 1-5 /usr/bin/find

Output:

minute        0 15 30 45
