The author discusses a bash script that can simulate the functionality of ‘ps aux’ without forking new processes. They propose using it in a scenario where all process IDs are taken, preventing the spawning of new processes. This tool is suggested for those familiar with bash/Linux. The author assures that it works on all machines in all situations, offering a clever solution to a common problem. However, the claim of it working in every scenario may be controversial.
