NAME

task-tutorial - A tutorial for the task(1) command line todo manager.

NOTE

Please note that this tutorial was written for task 1.7.0. Though it is still accurate on the general usage of task, it might not longer be 100% correct in all details. A new tutorial for task is planned for task 2.0.0.

DESCRIPTION

Task 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 commands that allow you to do various things with it.

30 second tutorial

For the excessively lazy. Add two tasks:

$ task add Read task documents later
$ task add priority:H Pay bills

Easy. See that second one has a High priority? Now let's look at those tasks:

$ task ls
ID Project Pri Description

 2         H   Pay bills

 1             Read task documents later

They are ordered by priority. Let's mark number 2 as done:

$ task 2 done
$ task ls
ID Project Pri Description

 1             Read task documents later

Gone. Now let's delete that remaining task, because, well, why bother now we are already using task:

$ task delete 1
$ task ls
No matches

That's how easy managing your task list can be. But now consider learning what task can really do...

Simple usage of task

Let us begin by adding some tasks:
$ task add Book plane ticket
$ task add Rent a tux
$ task add Reserve a rental car
$ task add Reserve a hotel room

You'll notice immediately that task has a very minimalist interface. Let us take a look at those tasks:

$ task ls
ID Project Pri Description

 1             Book plane ticket

 2             Rent a tux

 3             Reserve a rental car

 4             Send John a birthday card

The 'ls' command provides the most minimal list of tasks. Each task has been given an id number, and you can see that there are no projects or priorities assigned. Wait a minute - I own a tux, I don't need to rent one. Let us delete task 2:

$ task 2 delete
Permanently delete task? (y/n) y

Task wants you to confirm deletions. To suppress the confirmation, edit your .taskrc file and change the line:

confirmation=yes

to have a value of "no". If the entry is not there, then add it.

While the use of projects and priorities are not essential, they can be very useful when the list of tasks grows large. Let's assign projects to these tasks:

$ task 1 project:Wedding
$ task 3 project:Wedding
$ task 4 project:Family
$ task ls
ID Project Pri Description

 3 Family      Send John a birthday card

 2 Wedding     Reserve a rental car

 1 Wedding     Book plane ticket

Notice that the id numbers have changed. When tasks get deleted, or have their attributes changed (project, for example), the ids are prone to change. But the id numbers will remain valid until the next 'ls' command is run. You should only use the ids from the most recent 'ls' command. The ids change, because task is always trying to use small numbers so that it is easy for you to enter them correctly. Now that projects are assigned, we can look at just the Wedding project tasks:

Subprojects are supported. If you have a project "Wedding", you can specify that a task is a subproject "Transport" of "Wedding" by assigning the project "Wedding.Transport". Let's do this:

$ task 2 project:Wedding.Transport
$ task ls
ID Project Pri Description

 3 Family                Send John a birthday card

 2 Wedding.Transport     Reserve a rental car

 1 Wedding               Book plane ticket

Task matches the leftmost part of the project when searching, so projects may be abbreviated:

$ task ls project:Wedding.Tra
ID Project Pri Description

 2 Wedding.Transport     Reserve a rental car

This way of matching projects can be used to see all tasks under the "Wedding" project and all subprojects:

$ task ls project:Wedding
ID Project Pri Description

 2 Wedding.Transport     Reserve a rental car

 1 Wedding               Book plane ticket

Let's reassign 2 back to the "Wedding" project:

$ task 2 project:Wedding

Now that projects are assigned, we can look at just the Wedding project tasks:

$ task ls project:Wedding
ID Project Pri Description

 1 Wedding     Book plane ticket

 2 Wedding     Reserve a rental car

Any command arguments after the 'ls' are used for filtering the output. We could also have requested:

$ task ls ticket plane
ID Project Pri Description

 1 Wedding     Book plane ticket

Now let's prioritize. Priorities can be H, M or L (High, Medium, Low).

$ task ls
ID Project Pri Description

 3 Family      Send John a birthday card

 2 Wedding     Reserve a rental car

 1 Wedding     Book plane ticket
$ task 1 priority:H
$ task 2 prior:M
$ task 3 pr:H
Ambiguous attribute 'pr' - could be either of project, priority
$ task 3 pri:H
$ task ls
ID Project Pri Description

 3 Family  H   Send John a birthday card

 1 Wedding H   Book plane ticket

 2 Wedding M   Reserve a rental car

Notice that task supports the abbreviation of words such as priority and project. Priority can be abbreviated to pri, but not pr, because it is ambiguous. Now that tasks have been prioritized, you can see that the tasks are being sorted by priority, with the highest priority tasks at the top.

These attributes can all be provided when the task is added, instead of applying them afterwards, as shown. The following command shows how to set all the attributes at once:

$ task add project:Wedding priority:H Book plane ticket

The sequence of those arguments is not important, so you could have entered the following command instead:

$ task project:Wedding add Book plane priority:H ticket

This is because task knows what attributes look like (name:value), knows what commands it supports (add, ...), and just assumes the rest is part of the description. Incidentally, if you wanted 'priority:H' to be part of your task description, you need to fool task into ignoring it as an attribute. That can be done in two ways:

$ task add "quoting makes task consider priority:H part of one big argument" $ task add -- the hyphens make task treat everything after it as description

The 'ls' command provides the least information for each task. The 'list' command provides more:

$ task list
ID Project Pri Due Active Age Description

 3 Family  H              4 mins Send John a birthday card

 1 Wedding H              5 mins Book plane ticket

 2 Wedding M              5 mins Reserve a rental car

Notice that a task can have a due date, and can be active. The task lists are sorted by due date, then priority. Let's add due dates:

$ task 3 due:6/25/2008
$ task 1 due:7/31/2008
$ task list
ID Project Pri Due Active Age Description

 3 Family  H   6/25/2008        6 mins Send John a birthday card

 1 Wedding H   7/31/2008        7 mins Book plane ticket

 2 Wedding M                    7 mins Reserve a rental car

Note that due tasks may be colored to highlight the importance. See the task-color(5) man page for full details.

Tagging tasks is a good way to group them, aside from specifying a project. To add a tag to a task:

$ task <id> +tag

The plus sign indicates that this is a tag. Any number of tags may be applied to a task, and then used for searching. Tags are just single words that are labels.

$ task list
ID Project Pri Due Active Age Description

 3 Family  H   6/25/2008        8 mins Send John a birthday card

 1 Wedding H   7/31/2008        9 mins Book plane ticket

 2 Wedding M                    9 mins Reserve a rental car
$ task 1 +phone
$ task 2 +phone
$ task 3 +shopping
$ task 3 +john
$ task list +phone
ID Project Pri Due Active Age Description

 1 Wedding H   7/31/2008        9 mins Book plane ticket

 2 Wedding M                    9 mins Reserve a rental car

To remove a tag from a task, use the minus sign:

$ task 3 -john

To add a task that you have already completed, use the log command:

$ task log Notify postal service

This is equivalent to first adding a new task, then marking that new task as done. It is simple a shortcut.
