Resources
Taskwarrior (task) is a to-do list manager for the command line written in C++. It uses a simple human readable text file format to store to-do list items and associated metadata. Taskwarrior isn't tied to a specific school of thought on task organization. It's designed to be simple yet flexible and scalable. As such, Taskwarrior has a syntax that is simple and intuitive.
Notable features include:
- Data is stored locally in JSON files, easing migration to and from Taskwarror.
- Interactions can be scripted via Taskwarrior's Hooks API.
- Multiple UI options are available as part of the Taskwarrior ecosystem.
- When paired with app-misc/taskd, tasks can be shared with multiple remote client applications.
Installation
Emerge
root #emerge --ask app-misc/taskConfiguration
Environment variables
- $TASKRC allows the user to relocate the .taskrc configuration file to a desired directory.
- $TASKDATA allows the user to relocate the .task data file to a desired directory.
Modifying these variables is not required to enforce XDG Base Directory Support. If you've installed task warrior and it's ignoring you XDG preferences see the troubleshooting section.
Files
- ~/.config/task/taskrc — XDG local (per user) configuration file.
- ~/.local/share/task/* — XDG task list directory with tasks spread across multiple files.
- ~/.taskrc — legacy local (per user) configuration file.
- ~/.task/* — legacy local (per user) task list directory with tasks spread across multiple files.
Service
By itself, Taskwarrior is a single device application allowing all users on the device to have their own personal tasks lists. However, the Taskserver daemon provides a backend task server which provides for multiuser and multiclient support. Some smartphone applications, notably Foreground for Android, have begun to support this.
Usage
Basic usage is fairly intuitive, to list your exiting to-do items:
user $taskID Age Project Tag Due Description Urg ¯¯ ¯¯¯ ¯¯¯¯¯¯¯¯¯¯¯ ¯¯¯¯¯¯ ¯¯¯¯¯¯ ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ 1 2w gentoo-wiki ~1mo Add basic usage to ledger article 2.6 2 1w friends 5d Buy sam_ and ris a beer 1.4 3 3d home Clean out the garage. 0.2
To add a new task, simply type task add <task description> setting a due date and a project are optional but common for task organization purposes. Due dates do not necessarily require exact numeric dates. Taskwarrior has several human readable aliases such as eom for "end of month" and days of the week from which Taskwarrior can work out the date.
user $task add Pay the utility bills due:eom project:homeTo complete a task you need to reference its task number:
user $task 1 doneTask completion and task deletion aren't the same thing. In the former case, the task is moved a "completed" state but a record of it remains. If a task is deleted it is removed from the database. To delete an erroneously created task:
user $task 3 delTo generate a simple report for all tasks associated with a specific project task project:<project name> list. So, if you have an existing project called home and you want a list of all the associated tasks the command and its output should look something like this:
user $task project:home listID Age Project Tag Due Description Urg ¯¯ ¯¯¯ ¯¯¯¯¯¯¯¯¯¯¯ ¯¯¯¯¯¯ ¯¯¯¯¯¯¯¯¯¯ ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ 3 3d home Clean out the garage 0.2 4 1h home 2023-04-30 Pay the utility bills 0.1
Taskwarrior has many features burred below the surface. Numerous potential workflows are supported. The official Taskwarrior documentation is full of detail rich examples on how to get the most out of it.

Documentation for Taskwarrior can be found using 'man task', 'man taskrc', 'man task-color', 'man task-sync' or at https://taskwarrior.org
The general form of commands is:
task [<filter>] <command> [<mods>]
The <filter> consists of zero or more restrictions on which tasks to select, such as:
task <command> <mods>
task 28 <command> <mods>
task +weekend <command> <mods>
task project:Home due.before:today <command> <mods>
task ebeeab00-ccf8-464b-8b58-f7f2d606edfb <command> <mods>
By default, filter elements are combined with an implicit 'and' operator, but 'or' and 'xor' may also be used, provided parentheses are included:
task '(/[Cc]at|[Dd]og/ or /[0-9]+/)' <command> <mods>
A filter may target specific tasks using ID or UUID numbers. To specify multiple tasks use one of these forms:
task 1,2,3 delete
task 1-3 info
task 1,2-5,19 modify pri:H
task 4-7 ebeeab00-ccf8-464b-8b58-f7f2d606edfb info
The <mods> consist of zero or more changes to apply to the selected tasks, such as:
task <filter> <command> project:Home
task <filter> <command> +weekend +garden due:tomorrow
task <filter> <command> Description/annotation text
task <filter> <command> /from/to/ <- replace first match
task <filter> <command> /from/to/g <- replace all matches
Tags are arbitrary words, any quantity:
+tag The + means add the tag
-tag The - means remove the tag
Built-in attributes are:
description: Task description text
status: Status of task - pending, completed, deleted, waiting
project: Project name
priority: Priority
due: Due date
recur: Recurrence frequency
until: Expiration date of a task
limit: Desired number of rows in report, or 'page'
wait: Date until task becomes pending
entry: Date task was created
end: Date task was completed/deleted
start: Date task was started
scheduled: Date task is scheduled to start
modified: Date task was last modified
depends: Other tasks that this task depends upon
Attribute modifiers make filters more precise. Supported modifiers are:
Modifiers Example Equivalent Meaning
---------------- ----------------- ------------------- -------------------------
due:today due = today Fuzzy match
not due.not:today due != today Fuzzy non-match
before, below due.before:today due < today Exact date comparison
after, above due.after:today due >= tomorrow Exact date comparison
none project.none: project == '' Empty
any project.any: project !== '' Not empty
is, equals project.is:x project == x Exact match
isnt project.isnt:x project !== x Exact non-match
has, contains desc.has:Hello desc ~ Hello Pattern match
hasnt, desc.hasnt:Hello desc !~ Hello Pattern non-match
startswith, left desc.left:Hel desc ~ '^Hel' Beginning match
endswith, right desc.right:llo desc ~ 'llo$' End match
word desc.word:Hello desc ~ '\bHello\b' Boundaried word match
noword desc.noword:Hello desc !~ '\bHello\b' Boundaried word non-match
Alternately algebraic expressions support:
and or xor Logical operators
< <= = != >= > Relational operators
( ) Precedence
task due.before:eom priority.not:L list
task '(due < eom and priority != L)' list
The default .taskrc file can be overridden with:
task ... rc:<alternate file> ...
task ... rc:~/.alt_taskrc ...
The values in .taskrc (or alternate) can be overridden with:
task ... rc.<name>=<value> ...
task rc.color=off list
Any command or attribute name may be abbreviated if still unique:
task list project:Home
task li pro:Home
Some task descriptions need to be escaped because of the shell:
task add "quoted ' quote"
task add escaped \' quote
The argument -- tells Taskwarrior to treat all other args as description, even if they would otherwise be attributes or tags:
task add -- project:Home needs scheduling
Many characters have special meaning to the shell, including:
$ ! ' " ( ) ; \ ` * ? { } [ ] < > | & % # ~
Tips
This sections lists useful command that may not be obvious to find:
- List completed tasks for a project:
user $task completed project:test - Replace a description with spaces:
user $task 145 mod "/A Test/Not a test/"
Troubleshooting
Taskwarrior is not respecting the XDG Base Directory Specification
Taskwarrior defaults to ~/.taskrc. If ~/.taskrc is missing but ~./config/task/taskrc is present, the latter will be used. If both files are present, ~/.taskrc takes precedence. Thus, the file should first be moved, not just copied:
user $mkdir ~./config/task/user $mv ~/.taskrc ~./config/task/taskrcNext, edit ~./config/task/taskrc and uncomment the following lines:
FILE
~./config/task/taskrcdefault .taskrc configuration#data.location=~/.local/share/task
#hooks.location=~/.config/task/hooks
Next, move your existing ~/.task/ directory:
user $mkdir ~/.local/share/task/user $cp -r ~/.task/* ~/.local/share/task/Confirm the contents of the ~/.task directory have been copied properly and then delete the original directory.
user $rm -rf ~/.task/Next, copy the contents of ~/.task/hooks/ to the ~/.config/task/hooks/ directory:
user $cp -r ~/.task/hooks/* ~/.config/task/hooks/Finally, delete ~/.local/share/task/hooks/ if present and the original ~/.task directory:
user $rm -rf ~/.local/share/task/hooks/user $rm -rf ~/.taskRemoval
