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 for. This can be any application that takes a long time to complete, but is not resources intensive.
