Publishing ‘Tasks’ in Evolution.

with 3 comments


Well. .. why would anyone want to publish their tasks?

  • You are working in team and you want everybody to know what you r doing.
  • Status reports ?

Anyway here goes …

Your Evolution tasks are stored in ICAL format under $HOME/.evolution/tasks/local/

The default task list will be under $HOME/.evolution/tasks/local/system/task.ics

If you have more than one task list then you’ll find something like this.. .


I’m not sure why they have been named like this.. You need to find which tasks.ics = task list.

Thatz all we want to know.. Now itz time for writing some scripts to copy tasks.ics to your webserver. I want to publish this on a machine that runs 24/7. So we need to SCP this task.ics to the server. this can be done by a simple one line script and putit as a cronjob for syncing the changes automtically. something like

scp /home/jjohnny/.evolution/tasks/local/1155787868.6980.0@helios/tasks.ics johnny@

As you can see SCP is very simple to use. But it prompts for a password everytime you copy the file. Not good. This can be overriden by createing a ssh-key. Herez how to do it :

  1. Create a local ssh-key by using “ssh-keygen”. It’ll ask for passphrase (u could ignore it). Once the keys are generated you’ll have a public key and a private key. Public key will be in $HOME/.ssh/
  2. Copy to the server. “scp $HOME/.ssh/ myuser@myserver:~/
  3. Now log into ur server : “ssh -X myser@myserver”
  4. You should be able to find the public key (
  5. Now “cat ~/.ssh/authorized_keys”

Once that done you dont have to enter your password when u scp/ssh to the server. Now letz put the ‘one line’ script on a cronjob every five minutes. Now you evolution tasks are published and your team always updated.

Note : You may have to improve the script based on your needs. If your network is not reachable , cron will send a mail
to you complaining.
