This article shows you how to use the multi-threaded PowerShell module MultiThreadTaskRunner, which is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Application scenario

Multithreading is quite useful when you need to batch process some tasks, and it is also more helpful to make full use of the capabilities of existing computers. All major development languages support multithreading.

By default, PowerShell, as a scripting language, does not support multithreaded operations. Although there are so-called background tasks, it is actually quite troublesome to control.

Solution

I like PowerShell very much, so I wrote a custom module to implement multithreading. The module is written in C # and the source code can be accessed at the following address

Https://github.com/chenxizhang/MultiThreadTaskRunner

At the same time, this module has been packaged and released to Microsoft's official PowerShell Gallery

How to use

To use this module, you first need to install it (please open PowerSehll as an administrator)

Install-Module-Name MultiThreadTaskRunner

Next, prepare a script block for testing

$script = {

Param ($obj)

Write-Host $obj

}

Please note that this is only implemented in the simplest code, outputting data based on a parameter passed in

The third step, you can use it quickly.

New-MultiTaskJob-Source 1.. 100-Block $script-ThreadCount 10

What this command means is to use 10 parallel threads to process the 100 numbers passed in, and actually assign 10 numbers to each thread, and then execute it using the previously defined script block.

Please note that you can see that the output is not in the order of 1 to 100, which proves that these numbers are actually processed by different threads.
