Linux: 
Yata is a command line task manager that works on Windows, Mac, and Linux. The idea for it came because I was frustrated with the other alternatives I found and I really only wanted a simple task manager. I really wanted git, but for tasks. This is what yata wants to be.
Yata comes with 12 commands right now and each can be seen when you run
$ yata
$ yata help
$ yata --help
A basic workflow with Yata
$ yata add "Replace the bat signal lightbulb" # Creates a new task
$ yata list # Lists the current open tasks
1 Replace the bat signal lightbulb
$ yata complete 1 # Marks the task with ID 1 as completedTags are used to essentially label a task
Tags can be added in 2 ways
- Using the
--tagsflag allows you to specify a comma-delimited list of tags - Adding tags directly in the task description, prefixing the tag with a
#
$ yata add "Join the #fellowship"
$ yata add "Bring the ring to Mordor" --tags fellowship
$ yata list
1 Join the #fellowship [fellowship]
2 Bring the ring to Mordor [fellowship]Tasks can be marked with a single priority 1: Low 2: Normal 3: High
An important feature for me when developing this was to have the ability to push my tasks to a server and have the ability to download the tasks and essentially synchronize all my computers
Currently, Google Drive is the only server implementation
Follow the instructions found on "Step 1" here
You should have a file called client_secret.json at the end, which should be placed in your $HOME/.yata directory (For Windows users, it would be %USERPROFILE%/.yata)
Once that file is in the .yata directory, you can just push and Yata will walk you through the rest of the setup, which involves authorizing the Yata.
Note: You will also need to run yata config googledrive.secretfile client_secret.json
$ yata push -g # Pushes the tasks to Google Drive
$ yata fetch -g # Downloads the tasks found in Google Drive
$ yata merge # Merges the fetched tasks with the local tasks
