procfs

If you’ve ever wanted to enhance your Bash scripts by including detailed system information without relying on additional tools or utilities, then procfs (the virtual process file system) is your invaluable resource. Mostly used in Unix-like operating systems, procfs provides a more nuanced peek into your system directly from the file system. For Linux users, procfs is typically mounted at /proc, and it offers a treasure trove of data concerning system hardware and the running processes. This blog post will explore how to leverage procfs for extracting system information in Bash scripts. We will cover various commands and files within /proc that can be useful for scripting purposes.
