How to thread single-threaded applications

Introduction

CommandThreader is a command line tool that runs commands, line by line, but instead of it running only one at a time, it executes a batch of them so as one closes, it automatically starts a new command. The list of commands is provided via an input file
and the number of simultaneous running commands is specified as a number of allowed threads.

Implementation

Download and extract CommandThreader.zip (VirusTotal Scan Result) to a folder of your choice, on the computer that it will be scheduled to run on.

Demo Execution

In this demo, I execute a dummy application called DummyApp.exe. All this application does is delay for a random number of seconds and as a return code returns this numbers of seconds that it delays. This can
be any application that takes a long time to complete but is not resources intensive.

Input File

C:\Temp\DummyApp\DummyApp.exe|DummyArgument|C:\Temp\DummyApp|false|true|60
C:\Temp\DummyApp\DummyApp.exe|DummyArgument|C:\Temp\DummyApp|false|true|60
C:\Temp\DummyApp\DummyApp.exe|DummyArgument|C:\Temp\DummyApp|false|true|60
