How to Change Day-of-the-Week Setting for Scheduled Tasks in Windows Command Line

Introduction

In this article, we will discuss how to change the day-of-the-week setting for scheduled tasks in Windows Command Line. The SchTasks command line tool provides an easy and powerful way to manage scheduled tasks on Windows systems. However, changing the day-of-the-week setting for a scheduled task can be a bit tricky, especially if you want to use the command line. We will cover the key concepts related to scheduled tasks and the command line tool, and provide detailed examples with code blocks.

Understanding Scheduled Tasks and the SchTasks Tool

A scheduled task is a Windows function that allows you to run a program or script at a specific time or interval. The SchTasks tool is a command line utility that provides a way to manage scheduled tasks. You can use SchTasks to create, modify, delete, query, and run scheduled tasks.

To open the SchTasks tool, you can type "SchTasks" in the Command Prompt or Windows PowerShell window. When you run the SchTasks command without any options, it will display the list of scheduled tasks.

Changing Day-of-the-Week Setting for a Scheduled Task

To change the day-of-the-week setting for a scheduled task, you need to use the SchTasks command with the "change" option. The basic syntax is as follows:

Where:

• /change: specifies that the task is to be changed;
• /TN: specifies the name of the task;
• /ST: specifies the new start time;
• /D: specifies the day of the week for the task.

Setting Task to Run on Multiple Days of the Week

If you want to run the task on multiple days of the week, you can specify the days using bitwise OR operator

Here, we have set the task to run on Monday, Tuesday, and Wednesday.

Handling Invalid Arguments Error

When changing the day-of-the-week setting, you may encounter an "Invalid argument" error. This error occurs when the argument is not a valid day or time format.

Here's an example of an invalid argument:

The error occurs because "mon" is not a valid day of the week. The correct format is "MON" for Monday.
