task - A command line todo manager.
task <filter> <command> [ <mods> | <args> ]
Taskwarrior is a command line todo list manager. It maintains a list of
tasks that you want to do, allowing you to add/remove, and otherwise
manipulate them. Taskwarrior has a rich set of subcommands that allow
you to do various things with it.
At the core, taskwarrior is a list processing program. You add text and
additional related parameters and redisplay the information in a nice
way. It turns into a todo list program when you add due dates and
recurrence. It turns into an organized todo list program when you add
priorities, tags (one word descriptors), project groups, etc.
Taskwarrior turns into an organized to do list program when you modify
the configuration file to have the output displayed the way you want to
The <filter> consists of zero or more search criteria that select
tasks. For example, to list all tasks belonging to the 'Home' project:
task project:Home list
You can specify multiple filter terms, each of which further restrict
task project:Home +weekend garden list
This example applies three filters: the 'Home' project, the 'weekend'
tag, and the description or annotations must contain the character
sequence 'garden'. In this example, 'garden' is translated internally
as a convenient shortcut. The 'contains' here is an attribute
modifier, which is used to exert more control over the filter than
simply absence or presence. See 'ATTRIBUTE MODIFIERS' for a complete
list of modifiers.
Note that a filter may have zero terms, which means that all tasks
apply to the command. This can be dangerous, and this special case is
confirmed, and cannot be overridden. For example, this command:
task modify +work
This command has no filter, and will modify all tasks. Are you sure?
will add the 'work' tag to all tasks, but only after confirmation.
More filter examples:
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
task '( /[Cc]at|[Dd]og/ or /[0-9]+/ )' <command> <mods>
The parentheses isolate the logical term from any default command
filter or implicit report filter which would be combined with an
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/
Taskwarrior supports different kinds of commands. There are read
commands, write commands, miscellaneous commands and script helper
commands. Read commands do not allow modification of tasks. Write
commands can alter almost any aspect of a task. Script helper commands
are provided to help you write add-on scripts, for example, shell
Reports are read subcommands. There are several reports currently
predefined in taskwarrior. The output and sort behavior of these
reports can be configured in the configuration file. See also the man
page taskrc(5). There are also other read subcommands that are not
This is the only conventional command line argument that
Taskwarrior supports, and is intended for add-on scripts to
verify the version number of an installed Taskwarrior without
invoking the mechanisms that create default files.
With no command specified, the default command is run, and the
task <filter> active
Shows all tasks matching the filter that are started but not
task <filter> all
Shows all tasks matching the filter, including parents of
task <filter> blocked
Shows all tasks matching the filter, that have dependencies on
task <filter> burndown.daily
Shows a graphical burndown chart, by day. Note that 'burndown'
is an alias to the 'burndown.daily' report.
task <filter> burndown.weekly
Shows a graphical burndown chart, by week.
task <filter> burndown.monthly
Shows a graphical burndown chart, by month.
task calendar [due|<month> <year>|<year>] [y]
Shows a monthly calendar with due tasks marked. Shows one
horizontal line of months. If the 'y' argument is provided,
will show at least one complete year. If a year is provided,
such as '2012', then that full year is shown. If both a month
and a year are specified ('6 2012') then the months displayed
begin at the specified month and year. If the 'due' argument is
provided, will show the starting month of the earliest due task.
task colors [sample | legend]
Displays all possible colors, a named sample, or a legend
containing all currently defined colors.
Displays all supported columns and formatting styles. Useful
when creating custom reports.
task <filter> completed
Shows all tasks matching the filter that are completed.
task <filter> count
Displays only a count of tasks matching the filter.
task <filter> export
Exports all tasks in the JSON format. Redirect the output to a
file, if you wish to save it, or pipe it to another command or
script to convert it to another format. The standard task
release comes with a few example scripts, such as export-
task <filter> ghistory.annual
Shows a graphical report of task status by year.
task <filter> ghistory.monthly
Shows a graphical report of task status by month. Note that
'ghistory' is an alias to 'ghistory.monthly'.
Shows the long usage text.
task <filter> history.annual
Shows a report of task history by year.
task <filter> history.monthly
Shows a report of task history by month. Note that 'history' is
an alias to 'history.monthly'.
task <filter> ids
Applies the filter then extracts only the task IDs and presents
them as a range, for example: 1-4,12. This is useful as input
to a task command, to achieve this:
task $(task project:Home ids) modify priority:H
This example first gets the IDs for the project:Home filter,
then sets the priority to H for each of those tasks. This can
also be achieved directly:
task project:Home modify priority:H
This command is mainly of use to external scripts.
task <filter> uuids
Applies the filter then extracts only the task UUIDs and
presents them as a comma-separated list. This is useful as
input to a task command, to achieve this:
task $(task project:Home status:completed uuids) modify
This example first gets the UUIDs for the project:Home and
status:completed filter, then makes each of those tasks pending
This command is mainly of use to external scripts.

description matches an annotation exactly, the corresponding
annotation is deleted. If the provided description matches
annotations partly, the first partly matched annotation is
task <filter> done <mods>
Marks the specified task as done.
task <filter> duplicate <mods>
Duplicates the specified task and allows modifications.
task <filter> edit

distributing the changes made by the merge command. (See
'merge' command for valid URL syntax.)
task <filter> start <mods>
Marks the specified tasks as started.
task <filter> stop <mods>
Removes the start time from the specified task.
Miscellaneous subcommands either accept no command line arguments, or
accept non-standard arguments.
task config [name [value | '']]
Add, modify and remove settings directly in the taskwarrior
configuration. This command either modifies the 'name' setting
with a new value of 'value', or adds a new entry that is
equivalent to 'name=value':
task config name value
This command sets a blank value. This has the effect of
suppressing any default value:
task config name ''
Finally, this command removes any 'name=...' entry from the
task config name

a problem. When you report a bug, it is likely that the
platform, version, and environment are important. Running this
command generates a summary of similar information that should
accompany a bug report.
It includes compiler, library and software information. It does
not include any personal information, other than the location
and size of your task data files.
This command also performs a diagnostic scan of your data files
looking for common problems, such as duplicate UUIDs.

task <filter> _zshids
Shows the IDs and descriptions of matching tasks.
ATTRIBUTES AND METADATA
ID Tasks can be specified uniquely by IDs, which are simply the
index of the task in the data file. The ID of a task may
therefore change, but only when a command is run that displays
IDs. When modifying tasks, it is safe to rely on the last
displayed ID. Always run a report to check you have the right
ID for a task. IDs can be given to task as a sequence, for
task 1,4-10,19 delete
Tags are arbitrary words associated with a task. Use + to add a
tag and - to remove a tag from a task. A task can have any
quantity of tags.
Certain tags (called 'special tags'), can be used to affect the
way tasks are treated. For example, is a task has the special
tag 'nocolor', then it is exempt from all color rules. The
supported special tags are:
+nocolor Disable color rules processing for this task
+nonag Completion of this task suppresses all nag
+nocal This task will not appear on the calendar
+next Elevates task so it appears on 'next' report
Specifies the project to which a task is related to.
priority:H|M|L or priority:
Specifies High, Medium, Low and no priority for a task.
Specifies the due-date of a task.
Specifies the frequency of a recurrence of a task.
Specifies the Recurrence end-date of a task.
Specifies foreground color. Deprecated.
Specifies background color. Deprecated.
Specifies the desired number of tasks a report should show, if a
positive integer is given. The value 'page' may also be used,
and will limit the report output to as many lines of text as
will fit on screen. This defaults to 25 lines.
Date until task becomes pending.
Declares this task to be dependent on id1 and id2. This means
that the tasks id1 and id2 should be completed before this task.
Consequently, this task will then show up on the 'blocked'
For report purposes, specifies the date that a task was created.
The entry attribute cannot be directly specified using task add,
and should not be edited after creating the task.
Attribute modifiers improve filters. Supported modifiers are:
before (synonyms under, below)
after (synonyms over, above)
is (synonym equals)
isnt (synonym not)
has (synonym contains)
startswith (synonym left)
endswith (synonym right)
task due.before:eom priority.not:L list
The before modifier is used to compare values, preserving semantics, so
project.before:B list all projects that begin with 'A'. Priority 'L'
is before 'M', and due:2011-01-01 is before due:2011-01-02. The
synonyms 'under' and 'below' are included to allow filters that read
The after modifier is the inverse of the before modifier.
The none modifier requires that the attribute does not have a value.
task priority: list
task priority.none: list
are equivalent, and list tasks that do not have a priority.
The any modifier requires that the attribute has a value, but any value
The is modifier requires an exact match with the value.
The isnt modifier is the inverse of the is modifier.
The has modifier is used to search for a substring, such as:
task description.has:foo list
task foo list
These are equivalent and will return any task that has 'foo' in the
description or annotations.
The hasnt modifier is the inverse of the has modifier.
The startswith modifier matches against the left, or beginning of an
attribute, such that:
task project.startswith:H list
task project:H list
are equivalent and will match any project starting with 'H'. Matching
all projects not starting with 'H' is done with:
task project.not:H list
The endswith modifier matches against the right, or end of an
The word modifier requires that the attribute contain the whole word
specified, such that this:
task description.word:bar list
Will match the description 'foo bar baz' but does not match 'dog food'.
The noword modifier is the inverse of the word modifier.
EXPRESSIONS AND OPERATORS
You can use the following operators in filter expressions:
and or xor Logical operators
< <= = != >= > Relational operators
( ) Precedence
task due.before:eom priority.not:L list
task '( due < eom or priority != L )' list
Note that the parentheses are required when using a logical operator
other than the 'and' operator. The reason is that some report contains
filters that must be combined with the command line. Consider this
task project:Home or project:Garden list
While this looks correct, it is not. The 'list' report contains a
task show report.list.filter
Config Variable Value
Which means the example is really:
task status:pending project:Home or project:Garden list
The implied 'and' operator makes it:
task status:pending and project:Home or project:Garden list
This is a precedence error - the 'and' and 'or' need to be grouped
using parentheses, like this:
task status:pending and ( project:Home or project:Garden ) list
The original example therefore must be entered as:
task '( project:Home or project:Garden )' list
This includes quotes to escape the parentheses, so that the shell
doesn't interpret them and hide them from taskwarrior.
There is redundancy between operators, attribute modifiers and other
syntactic sugar. For example, the following are all equivalent:
task foo list
task /foo/ list
task description.contains:foo list
task description.has:foo list
task 'description ~ foo' list
SPECIFYING DATES AND FREQUENCIES
Taskwarrior reads dates from the command line and displays dates in the
reports. The expected and desired date format is determined by the
configuration variable dateformat in the taskwarrior configuration
task ... due:7/14/2008
task ... due:20120314T223000Z
task ... due:today
task ... due:yesterday

Recurrence periods. Taskwarrior supports several ways of specifying the
frequency of recurring tasks.
daily, day, 1da, 2da, ...
Every day or a number of days.
Mondays, Tuesdays, Wednesdays, Thursdays, Fridays and
skipping weekend days.
weekly, 1wk, 2wks, ...
Every week or a number of weeks.
Every two weeks.
monthly, month, 1mo, 2mo, ...
quarterly, 1qtr, 2qtrs, ...
Every three months, a quarter, or a number of quarters.
Every six months.
annual, yearly, 1yr, 2yrs, ...
Every year or a number of years.
biannual, biyearly, 2yr
Every two years.
All taskwarrior commands may be abbreviated as long as a unique prefix
is used, for example:
$ task li
is an unambiguous abbreviation for
$ task list
$ task l
could be list, ls or long.
Note that you can restrict the minimum abbreviation size using the
Some task descriptions need to be escaped because of the shell and the
special meaning of some characters to the shell. This can be done
either by adding quotes to the description or escaping the special
$ task add "quoted ' quote"
$ task add escaped \' quote
The argument -- (a double dash) tells taskwarrior to treat all other
args as description:
$ task add -- project:Home needs scheduling
In other situations, the shell sees spaces and breaks up arguments.
For example, this command:
$ task 123 modify /from this/to that/
is broken up into several arguments, which is corrected with quotes:
$ task 123 modify "/from this/to that/"
It is sometimes necessary to force the shell to pass quotes to
Taskwarrior intact, so you can use:
$ task add project:\'Three Word Project\' description
CONFIGURATION FILE AND OVERRIDE OPTIONS
Taskwarrior stores its configuration in a file in the user's home
directory: ~/.taskrc. The default configuration file can be overridden
task rc:<path-to-alternate-file> ...
Specifies an alternate configuration file.
The environment variable overrides the default and the command line
specification of the .taskrc file.
task rc.<name>:<value> ...
task rc.<name>=<value> ... Specifies individual configuration
TASKDATA=/tmp/.task task ...
The environment variable overrides the default, the command
line, and the 'data.location' configuration setting of the task
