NAME
task - A command line todo manager.

SYNOPSIS
task <filter> <command> [ <mods> | <args> ]
task --version

DESCRIPTION
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.

FILTER
The <filter> consists of zero or more search criteria that select tasks. For example, to list all pending tasks belonging to the 'Home' project:
  task project:Home list
You can specify multiple filter terms, each of which further restricts the result:
  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 to:
  description.contains:garden
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 the section 'ATTRIBUTE MODIFIERS' below 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? (yes/no)
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 +bills due.by:eom                    <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>
The parentheses isolate the logical term from any default command filter or implicit report filter which would be combined with an implicit 'and'. A filter may target specific tasks using ID or UUID numbers. To specify multiple tasks use one of these forms (space-separated list of ID numbers, UUID numbers or ID ranges):
  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
Note that it may be necessary to properly escape special characters as well as quotes in order to avoid their special meanings in the shell. See also the section 'SPECIFYING DESCRIPTIONS' for more information.

MODIFICATIONS
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

SUBCOMMANDS
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 completion (only minimal output is generated, as with verbose=nothing). Those commands which are explicitly affected by the context are denoted as such.

READ SUBCOMMANDS
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 reports.

task --version
    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.

task <filter>
    With no command specified, the default command is run, and the filter applied.

task <filter> active
    Shows all tasks matching the filter that are started but not completed.

task <filter> all
    Shows all tasks matching the filter, including parents of recurring tasks.

task <filter> blocked
    Shows all tasks matching the filter, that are currently blocked by other tasks.

task <filter> blocking
    Shows all tasks matching the filter, that block other tasks.

task <filter> burndown.daily
    Shows a graphical burndown chart, by day. Is affected by the context.

task <filter> burndown.weekly
    Shows a graphical burndown chart, by week. Note that 'burndown' is an alias to the 'burndown.weekly' report. Is affected by the context.

task <filter> burndown.monthly
    Shows a graphical burndown chart, by month. Is affected by the context.

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 '2015', then that full year is shown. If both a month and a year are specified ('6 2015') 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.

task columns [<substring>]
    Displays all supported columns and formatting styles. Useful when creating custom reports. If a substring is provided, only matching column names are shown.

task commands
    Shows all the supported commands, with some details of each.

task <filter> completed
    Shows all tasks matching the filter that are completed.

task <filter> count
    Displays only a count of tasks matching the filter. Is affected by the context.

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. You'll find these example scripts online at <https://taskwarrior.org/tools/>:
      export-csv.pl
      export-sql.py
      export-xml.py
      export-yaml.pl
      export-html.pl
      export-tsv.pl

task <filter> ghistory.weekly
    Shows a graphical report of task status by week.

task <filter> ghistory.daily
    Shows a graphical report of task status by day.

task help
    Shows the long usage text.

task <filter> history.annual
    Shows a report of task history by year. Is affected by the context.

task <filter> history.monthly
    Shows a report of task history by month. Note that 'history' is an alias to 'history.monthly'. Is affected by the context.

task <filter> history.weekly
    Shows a report of task history by week. Is affected by the context.

task <filter> history.daily
    Shows a report of task history by day. Is affected by the context.

task <filter> ids
    Applies the filter then extracts only the task IDs and presents them as a space-separated list. 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 on all tasks (even deleted and completed tasks) then extracts only the task UUIDs and presents them as a space-separated list. This is useful as input to a task command, to achieve this:
      task $(task project:Home status:completed uuids) modify status:pending
    This example first gets the UUIDs for the project:Home and status:completed filters, then makes each of those tasks pending again. This command is mainly of use to external scripts.

task udas
    Shows a list of UDAs that are defined, including their name, type, label and allowed values. Also shows UDA usage and any orphan UDAs.

task <filter> information
    Shows all data and metadata for the specified tasks. This is the only means of displaying all aspects of a given task, including the change history.

task <filter> list
    Provides a standard listing of tasks matching the filter.

task <filter> oldest
    Shows the oldest tasks matching the filter.

task <filter> overdue
    Shows all incomplete tasks matching the filter that are beyond their due date.

task <filter> projects
    Lists all project names that are currently used by pending tasks, and the number of tasks for each. Is affected by the context.

task <filter> waiting
    Shows all waiting tasks matching the filter.

WRITE SUBCOMMANDS

task add <mods>

task <filter> delete <mods>
    Deletes the specified task from task list. Is affected by the context.

task <filter> denotate <mods>
    Deletes an annotation for the specified task. If the provided description matches an annotation exactly, the corresponding annotation is deleted. If the provided description matches annotations partly, the first partly matched annotation is deleted. Is affected by the context.

task <filter> done <mods>
    Marks the specified task as done. Is affected by the context.

task <filter> duplicate <mods>
    Duplicates the specified task and allows modifications. Is affected by the context.

task <filter> edit
    Launches a text editor to let you modify all aspects of a task directly. In general, this is not the recommended method of modifying tasks, but is provided for exceptional circumstances. Use carefully. Is affected by the context.

task import [<file> ...]
    Imports tasks in the JSON format. Can be used to add new tasks, or update existing ones. Tasks are identified by their UUID. If no file or "-" is specified, import tasks from STDIN. Setting rc.recurrence.confirmation to an appropriate level is recommended if import is to be used in automated workflows. See taskrc(5). For importing other file formats, the standard task release comes with a few example scripts, such as:
      import-todo.sh.pl
      import-yaml.pl

task import-v2
    Imports tasks from the Taskwarrior v2.x format. This is used when upgrading from version 2.x to version 3.x.

task log <mods>
    Adds a new task that is already completed, to the task list. It is affected by the currently set context.

task <filter> modify <mods>
    Modifies the existing task with provided information.

task <filter> prepend <mods>
    Prepends description text to an existing task. Is affected by the context.

task <filter> purge
    Permanently removes the specified tasks from the data files. Only tasks that are already deleted can be purged. This command has a local-only effect and changes introduced by it are not synced. Is affected by the context. Warning: causes permanent, non-revertible loss of data.

task <filter> start <mods>
    Marks the specified tasks as started. Is affected by the context.

task <filter> stop <mods>
    Removes the start time from the specified task. Is affected by the context.

MISCELLANEOUS SUBCOMMANDS
Miscellaneous subcommands either accept no command line arguments, or accept non-standard arguments.

task calc <expression>
    Evaluates an algebraic expression. Can be used to test how Taskwarrior parses and evaluates the expression given on the command line. Examples:
        task calc 1 + 1
        2
        task calc now + 8d
        2015-03-26T18:06:57
        task calc eom
        2015-03-31T23:59:59

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 .taskrc file:
        task config name

task context <name>
    Sets the currently active context. See the CONTEXT section. Example:
        task context work

task context delete <name>
    Deletes the context with the name <name>. If the context being deleted is currently set as active, it will be unset. Example:
        task context delete work

task context define <name> <filter>
    Defines a new context with name <name> and definition <filter>. This command does not affect the currently set context, just adds a new context definition. Examples:
        task context define work project:Work
        task context define home project:Home or +home
        task context define superurgent due:today and +urgent

task context list
    Outputs a list of available contexts along with their definitions.

task context none
    Clears the currently active context, if any was set.

task context show
    Shows the currently active context, along with its definition.

task diagnostics
    Shows diagnostic information, of the kind needed when reporting 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 of your task data. This command also performs a diagnostic scan of your data looking for common problems, such as duplicate UUIDs.

task execute <external command>
    Executes the specified command. Not useful by itself, but when used in conjunction with aliases and extensions can provide seamless integration.

task logo
    Displays the Taskwarrior logo.

task news
    Guides the user through important release notes anytime a new version of Taskwarrior is installed. It provides personalized feedback, deprecation warnings and usage advice, where applicable.

task reports
    Lists all supported reports. This includes the built-in reports, and any custom reports you have defined.

task show [all | <substring>]
    Shows all the current settings. If a substring is specified just the settings containing that substring will be displayed.

task <filter> stats
    Shows statistics of the tasks defined by the filter. Is affected by the context.

task <filter> summary
    Shows a report of aggregated task status by project. Is affected by the context.

task sync
    The sync command synchronizes data with the Taskserver, if configured. Note: If you use multiple sync clients, make sure this setting (which is the default) is on your primary client:
      recurrence=on
    and on all other clients (this is not the default):
      recurrence=off
    This is a workaround to avoid a recurrence bug that duplicates recurring tasks.

task <filter> tags
    Show a list of all tags used. Any special tags used are highlighted. Note that virtual tags are not listed - they don't really exist, and are just a convenient notation for other task metadata. It is an error to attempt to add or remove a virtual tag. Is affected by the context.

task timesheet [<weeks>]
    Shows a weekly report of tasks completed and started.

task undo
    Reverts the most recent action. Obeys the confirmation setting.

task version
    Shows the Taskwarrior version number.

      $ task _get 2.due.year
      2015
    For a full list of supported attribute-specific DOM references, consult the online documentation at: <https://taskwarrior.org/docs/dom.html>

ATTRIBUTES AND METADATA

ID  Tasks can be specified uniquely by IDs, which are the indexes of the "working set" of tasks (mostly pending and recurrent tasks). The ID of a task may therefore change, but only when a report that displays IDs is run. 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 example:
    task 1,4-10,19 delete

+tag|-tag
    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, if 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 messages
        +nocal       This task will not appear on the calendar
        +next        Elevates task so it appears on 'next' report
    There are also virtual tags, which represent task metadata in tag form. These tags do not exist, but can be used to filter tasks. The supported virtual tags are:
        ACTIVE       Matches if the task is started
        ANNOTATED    Matches if the task has annotations
        BLOCKED      Matches if the task is blocked
        BLOCKING     Matches if the task is blocking
        CHILD        Matches if the task has a parent (deprecated in 2.6.0)
        COMPLETED    Matches if the task has completed status
        DELETED      Matches if the task has deleted status
        DUE          Matches if the task is due within the next 7 days (See rc.due)
        INSTANCE     Matches if the task is a recurrent instance
        LATEST       Matches if the task is the newest added task
        MONTH        Matches if the task is due this month
        ORPHAN       Matches if the task has any orphaned UDA values
        OVERDUE      Matches if the task is overdue
        PARENT       Matches if the task is a parent (deprecated in 2.6.0)
        PENDING      Matches if the task has pending status
        PRIORITY     Matches if the task has a priority
        PROJECT      Matches if the task has a project
        QUARTER      Matches if the task is due this quarter
        READY        Matches if the task is actionable
        SCHEDULED    Matches if the task is scheduled
        TAGGED       Matches if the task has tags
        TEMPLATE     Matches if the task is a recurrence template
        TODAY        Matches if the task is due today
        TOMORROW     Matches if the task is due sometime tomorrow
        UDA          Matches if the task has any UDA values
        UNBLOCKED    Matches if the task is not blocked
        UNTIL        Matches if the task expires
        WAITING      Matches if the task is waiting
        WEEK         Matches if the task is due this week
        YEAR         Matches if the task is due this year
        YESTERDAY    Matches if the task was due sometime yesterday
    You can use +BLOCKED to filter blocked tasks, or -BLOCKED for unblocked tasks. Similarly, -BLOCKED is equivalent to +UNBLOCKED. It is an error to attempt to add or remove a virtual tag.

project:<project-name>
    Specifies the project to which a task is related to.

status:pending|deleted|completed|waiting|recurring
    Specifies the state of the task.

priority:H|M|L or priority:
    Specifies High, Medium, Low and no priority for a task.

due:<due-date>
    Specifies the due-date of a task.

recur:<frequency>
    Specifies the frequency of a recurrence of a task.

scheduled:<ready-date>
    Specifies the date after which a task can be accomplished.

until:<expiration date of task>
    Specifies the expiration date of a task, after which it will be deleted.

limit:<number-of-rows>
    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.

wait:<wait-date>
    When a task is given a wait date, it is hidden from most built-in reports, which exclude +WAITING. When the date is in the past, the task is not considered +WAITING, and again becomes visible. Note that, for compatibilty, such tasks are shown as having status "waiting", but this will change in a future release.

depends:<id1,id2 ...>
    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' report. It accepts a comma-separated list of ID numbers, UUID numbers and ID ranges. When prefixing any element of this list by '-', the specified tasks are removed from the dependency list.

entry:<entry-date>
    For report purposes, specifies the date that a task was created.

modified:<modified-date>
    Specifies the most recent modification date.

ATTRIBUTE MODIFIERS
Attribute modifiers improve filters. Supported modifiers are:
    before (synonyms under, below)
    after (synonyms over, above)
    by
    none
    any
    is (synonym equals)
    isnt (synonym not)
    has (synonym contains)
    hasnt
    startswith (synonym left)
    endswith (synonym right)
    word
    noword
They can be applied to all regular attributes (see above) and the following calculated attributes:
    urgency (or short urg)
For example:
    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 more naturally. The after modifier is the inverse of the before modifier. The by modifier is the same as 'before', except it also includes the moment in question. For example:
    task add test due:eoy
will be found when using the inclusive filter 'by':
    task due.by:eoy
but not when the non-inclusive filter 'before' is used:
    task due.before:eoy
this applies equally to other named dates such as 'eom', 'eod', etc; the modifier compares using '<=' rather than '<' like 'before' does. The none modifier requires that the attribute does not have a value. For example:
    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 will suffice. 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 attribute. The word modifier requires that the attribute contain the whole word specified, such that this:
    task description.word:foo 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
For example:
  task due.before:eom priority.not:L list
  task '( due < eom or priority != L )' list
  task '! ( project:Home or project:Garden )' list
The = operator tests for approximate equality. Dates compare equal if they are on the same day (hour and minutes are ignored). Strings compare equal if the left operand starts with the right operand. The == operator tests for exact equality. The != and !== operators are the negation of = and == respectively. The negation operator is !. Note that the parentheses are required when using a logical operator other than the 'and' operator. The reason is that some reports contain filters that must be combined with the command line. Consider this example:
  task project:Home or project:Garden list
While this looks correct, it is not. The 'list' report contains a filter of:
  task show report.list.filter
  Config Variable    Value
  -----------------  --------------
  report.list.filter status:pending
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

  DATES
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

    Exact specification

  FREQUENCIES
Recurrence periods. Taskwarrior supports several ways of specifying the frequency of recurring tasks. Note that frequencies can be abbreviated.

    daily, day, 1day, 1days, 2day, 2days, 1da, 2da, ...
        Every day or a number of days.

    weekdays
        Mondays, Tuesdays, Wednesdays, Thursdays, Fridays and skipping weekend days.

    weekly, 1wk, 2wks, ...
        Every week or a number of weeks.

    biweekly, fortnight
        Every two weeks.

    monthly, month, 1mo, 2mo, ...
        Every month.

    quarterly, 1qtr, 2qtrs, ...
        Every three months, a quarter, or a number of quarters.

    semiannual
        Every six months.

    annual, yearly, 1yr, 2yrs, ...
        Every year or a number of years.

    biannual, biyearly, 2yr
        Every two years.

CONTEXT
Context is a user-defined query, which is automatically applied to all commands that filter the task list and to commands that create new tasks (add, log). For example, any report command will have its result affected by the current active context. Here is a list of the commands that are affected:
    add
    burndown
    count
    delete
    denotate
    done
    duplicate
    edit
    history
    log
    prepend
    projects
    purge
    start
    stats
    stop
    summary
    tags
All other commands are NOT affected by the context.
    $ task list
    ID Age Project  Description        Urg
    1  2d  Sport    Run 5 miles        1.42
    2  1d  Home     Clean the dishes   1.14
    $ task context home
    Context 'home' set. Use 'task context none' to remove.
    $ task list
    ID Age Project  Description        Urg
    2  1d  Home     Clean the dishes   1.14
    Context 'home' set. Use 'task context none' to remove.
Task list got automatically filtered for project:Home.
    $ task add Vaccuum the carpet
    Created task 3.
    Context 'home' set. Use 'task context none' to remove.
    $ task list
    ID Age Project  Description         Urg
    2  1d  Home     Clean the dishes    1.14
    3  5s  Home     Vaccuum the carpet  1.14
    Context 'home' set. Use 'task context none' to remove.
Note that the newly added task "Vaccuum the carpet" has "project:Home" set automatically. As seen in the example above, context is applied by specifying its name to the "context" command. To change the currently applied context, just pass the new context's name to the 'context' command. To unset any context, use the 'none' subcommand.
    $ task context none
    Context unset.
    $ task list
    ID Age Project  Description         Urg
    1  2d  Sport    Run 5 miles         1.42
    2  1d  Home     Clean the dishes    1.14
    3  7s  Home     Vaccuum the carpet  1.14
Context can be defined using the 'define' subcommand, specifying both the name of the new context, and it's assigned filter.
    $ task context define home project:Home
    Are you sure you want to add 'context.home.read' with a value of 'project:Home'? (yes/no) yes
    Are you sure you want to add 'context.home.write' with a value of 'project:Home'? (yes/no) yes
    Context 'home' successfully defined.
Note that you were separately prompted to set the 'read' and 'write' context. This allows you to specify contexts that only work for reporting commands or only for commands that create tasks. To remove the definition, use the 'delete' subcommand.
    $ task context delete home
    Are you sure you want to remove 'context.home.read'? (yes/no) yes
    Are you sure you want to remove 'context.home.write'? (yes/no) yes
    Context 'home' deleted.
To check what is the currently active context, use the 'show' subcommand.
    $ task context show
    Context 'home' with
    * read filter: '+home'
    * write filter: '+home'
    is currently applied.
Contexts can store arbitrarily complex filters.
    $ task context define family project:Family or +paul or +nancy
    Are you sure you want to add 'context.family.read' with a value of 'project:Family or +paul or +nancy'? (yes/no) yes
    Are you sure you want to add 'context.family.write' with a value of 'project:Family or +paul or +nancy'? (yes/no) no
    Context 'family' successfully defined.
Contexts are permanent, and the currently set context name is stored in the "context" configuration variable. The context definition is stored in the "context.<name>.read" configuration variable (for reporting commands) and "context.<name>.write" configuration variable (for task additions, i.e. task add/log). Note that in the example above, the user decided not to define the complex filter as writeable context. The reason for this decision is that the complex filter in the example does not directly translate to a modification. In fact, if such a context is used as a writeable context, the following happens:
    $ task add Call Paul
    Created task 4.
    Context 'family' set. Use 'task context none' to remove.
    $ task 4 list
    ID Age  Project Tags       Description      Urg
     4 9min Family  nancy paul or or Call Paul    0
There is no clear mapping between the complex filter used and the modifications (should only the project be set? only the tags? both?). Additionally note the 'or' operators being present in the description. Taskwarrior does not try to guess the user intention here, and instead, the user is expected to set the "context.<name>.write" variable to make their intention explicit, for example:
    $ task config context.family.write project:Family
    Are you sure you want to change the value of 'context.family.write' from 'project:Family or +paul or +nancy' to 'project:Family'? (yes/no) yes
    Config file /home/tbabej/.config/task/taskrc modified.
    $ task context
    Name   Type  Definition                        Active
    family read  project:Family or +paul or +nancy yes
           write project:Family                    yes
    home   read  +home                             no
           write +home                             no
Note how read and write contexts differ for context "family", while for context "home" they stay the same. In addition, every configuration parameter can be overridden for the current context, by specifying context.<name>.rc.<parameter>. For example, if the default command for the family context should be displaying the family_report:
    $ task config context.family.rc.default.command family_report

COMMAND ABBREVIATION
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
but
  $ task l
could be list, ls or long. Note that you can restrict the minimum abbreviation size using the configuration setting:
  abbreviation.minimum=3

SPECIFYING DESCRIPTIONS
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 character:
  $ 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
Taskwarrior supports Unicode using only the UTF8 encoding.

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 with:

task rc:<path-to-alternate-file> ...
    Specifies an alternate configuration file with highest priority.

TASKRC=<path-to-alternate-file> task ..
    The environment variable specifies an alternate configuration file to use.

XDG_CONFIG_HOME=<path-to-alternate-config-home> task ..
    The environment variable specifies an alternate configuration file to use.

task rc.<name>:<value> ...
    task rc.<name>=<value> ... Specifies individual configuration file overrides.

TASKDATA=/tmp/.task task ...
    The environment variable overrides the default, and the 'data.location' configuration setting of the task data directory.

FILES

~/.taskrc
    User configuration file - see also taskrc(5). Note that this can be overridden on the command line or by the TASKRC environment variable. Also, if ~/.taskrc doesn't exist and XDG_CONFIG_HOME environment variable is defined, taskwarrior will check if $XDG_CONFIG_HOME/task/taskrc exists and attempt to read it

~/.task
    The default directory where task stores its data. The location can be configured in the configuration variable 'data.location', or overridden with the TASKDATA environment variable.

~/.task/taskchampion.sqlite3
    The database file.
