How to use the command "pueue pause" (with examples)

The pueue pause command is used to pause running tasks or groups in the Pueue task management system. It allows users to temporarily halt the execution of tasks and prevent new tasks from starting. This command can be useful when you need to stop the execution of certain tasks or temporarily prevent new tasks from starting.

Use case 1: Pause all tasks in the default group

Code:

pueue pause

Motivation:

Pausing all tasks in the default group can be helpful when you want to temporarily stop the execution of all tasks. This can be useful, for example, when troubleshooting or when you need to free up system resources for other processes.

Explanation:

The command pueue pause with no arguments pauses all tasks in the default group. By default, tasks are placed in the default group when no group name is specified.

Example output:

[INFO] Pausing all tasks in group 'default'

Use case 2: Pause a running task

Code:

pueue pause task_id

Motivation:

Pausing a specific running task can be useful when you want to temporarily pause the execution of that particular task. This can be helpful when you need to focus on another task or when you want to investigate an issue with the paused task.

Explanation:

The command pueue pause task_id pauses the task with the specified task ID. You need to replace task_id with the actual ID of the task you want to pause.

Example output:

[INFO] Pausing task with ID 42

Use case 3: Pause a running task and stop all its direct children

Code:

pueue pause --children task_id

Motivation:

Pausing a running task and stopping all its direct children can be helpful when you want to halt the execution of a task and prevent its child processes from continuing. This can be useful, for example, when you want to stop a task and all its immediate child processes.

Explanation:

The command pueue pause --children task_id pauses the task with the specified task ID and stops all its direct children. By stopping the direct children, it prevents them from continuing their execution.

Example output:

[INFO] Pausing task with ID 42 and stopping all its direct children

Use case 4: Pause all tasks in a group and prevent it from starting new tasks

Code:

pueue pause --group group_name

Motivation:

Pausing all tasks in a specific group and preventing it from starting new tasks can be useful when you want to temporarily stop the execution of a group of related tasks. This can be helpful, for example, when you need to focus on another group of tasks or when you want to prevent new tasks from starting in a particular group temporarily.

Explanation:

The command pueue pause --group group_name pauses all tasks in the specified group and prevents it from starting new tasks. You need to replace group_name with the actual name of the group you want to pause.

Example output:

[INFO] Pausing all tasks in group 'important_tasks' and preventing it from starting new tasks

Use case 5: Pause all tasks and prevent all groups from starting new tasks

Code:

pueue pause --all

Motivation:

Pausing all tasks and preventing all groups from starting new tasks can be useful when you want to temporarily halt the execution of all tasks and prevent new tasks from starting in any group. This can be helpful, for example, when you need to free up system resources or when you want to ensure that no new tasks are started at a specific time.

Explanation:

The command pueue pause --all pauses all tasks and prevents all groups from starting new tasks. This command affects all groups and stops the execution of all tasks, regardless of their group membership.

Example output:

[INFO] Pausing all tasks and preventing all groups from starting new tasks

Conclusion:

The pueue pause command provides a way to pause running tasks or groups in the Pueue task management system. By using different arguments, you can pause specific tasks, stop their direct children, or pause entire groups and prevent them from starting new tasks. This command can be useful when you need to temporarily halt task execution, investigate issues, or manage task groups effectively.
