.SH SYNOPSIS
.B task [subcommand] [args]
.B task <filter> <command> [ <mods> | <args> ]
.SH 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.
Task has a rich list of subcommands that allow you to do various things with it.

list program when you modify the configuration file to have the output displayed
the way you want to see it.
.SH FILTER
The <filter> consists of zero or more search criteria to select. For example,
to list all tasks belonging to the 'Home' project:
task project:Home list
You can specify multiple filters, each of which further restrict the results:
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 characters '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 'ATTRIBUTE MODIFIERS' for a complete list of modifiers.
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 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.
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
.SH 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/
.SH 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.
.SH 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.

.SH EXPRESSIONS AND OPERATORS
You can use the following operators in filter expressions:
and or xor Logical operators
< <= = != >= > Relational operators
+ - Addition, subtraction
! Inversion
~ !~ Match, no match
( ) Precedence
For example:
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 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
