Free task scheduler software for linux

The Job Scheduler runs executable files, shell scripts and database procedures automatically (MySQL, PostgreSQL, Firebird and SQL Server, Oracle, DB2).

Job Scheduler processes sequential and parallel tasks and job chains, provides an API for job implementation with Java, Javascript, VBScript, Perl and exposes jobs as Web Services.

Java iCal Group Scheduler enables several users to get together for a meeting, by using JICAL to translate their iCalendar files into their available free/busy time and post it automatically to your Web server.

This project enables Ximian Evolution desktop users to book meetings with each other (and Outlook users) via a Web server storing their Free/Busy information as specified in RFC2445.

It works with Evolution, Korganiser, Apple iCal, and MS Outlook (for meetings), and enhances your workgroup and personal calendar views. Shell scripts for converting to various image formats are also included.

Task Coach is a simple open source todo manager to manage personal tasks and todo lists. Task Coach grew out of my frustration that well-known task managers, such as those provided with Outlook or Lotus Notes, do not provide facilities for composite tasks.
Often, tasks and other things todo consist of several activities. Task Coach is designed to deal with composite tasks.
Currently, Task Coach is at version 0.42. I use it on a daily basis, but there are still a lot of features missing. If theres anything youd like to see included, please let me know.
Main features:
- Creating, editing, and deleting tasks and subtasks.
- Tasks have a subject, description, priority, start date, due date and a completion date.
- Tasks can be viewed as a list or as a tree.
- Tasks can be sorted by all task attributes, e.g. subject, budget, budget left, due date, etc.
- Several filters to e.g. hide completed tasks or view only tasks that are due today.
- Task status depends on its subtask and vice versa. E.g. if you mark the last uncompleted subtask as completed, the parent task is automatically marked as completed too.
- Tasks can be assigned to user-defined categories.
- Settings are persistent and saved automatically. The last opened file is loaded automatically when starting Task Coach.
- Track time spent on tasks. Tasks can have a budget. Time spent can be viewed by individual effort period, by day, by week, and by month.
- The Task Coach file format (.tsk) is XML.
Enhancements:
- This release fixes sorting of tasks by priority and makes sure that Task Coach does not block OS shutdown.

Tasks project is a simple to do list application that uses libecal, part of Embedded Evolution Data Server.

BORG is a combination calendar and task tracking system. The calendar supports simple todos. The Task Tracker goes way beyond todos.
BORG is basically meant to be a small self-contained Java application that you can run locally. Many users run BORG Calendar and Task Tracker from a thumb drive.
BORG actually stands for Berger-Organizer. Unfortunately, the name BORG seems to be a popular choice for software products, probably due to the number of Star Trek fans that write code. The fact that BORG calendar also seems to refer to the Microsoft Outlook calendar makes things even more confusing. Oh well....
Why would anyone want to use a home-grown calendar/task tracker when there are so many others out there, freeware and otherwise?
A potential BORG user might agree with the following:
- I use a calendar/task tracker to remind me to do everything in life that I have to do.
- I do not want to set up a web server just to see my calendar
- I do not want to access the internet to see my calendar
- I work on Linux, Windows and other OSs and would like any of my machines to run my calendar program
- I dont want to have to worry about my calendar not working if I upgrade linux, windows, glibc, mySQL, apache, < fill in any third-party software that causes things to stop working >, etc...
- I like open source software. Even if the developer(s) die, I can still build and enhance my calendar program.
Main features:
- Nice Month-at-a-time view
- To-Do list
- Month-print

- The Task Tracker tracks issues and tasks through a set of states with start and end dates, sub-tasks, descriptions, and resolutions.
- Pop-up reminders
- Email reminders
- User tunable task types and state transitions in the task tracker
