Pid | Vid

Let’s break down what these two acronyms mean, how they work together, and why knowing them can save you hours of frustration. PID stands for Process Identifier . It’s a unique number assigned to every running process on Linux, macOS, Windows, or any Unix-like operating system.

lsusb # Bus 002 Device 003: ID 046d:c52b Logitech, Inc. # 046d = Vendor ID (Logitech), c52b = Product ID In this case, refers to the Product ID & Vendor ID pair. 3. VIRTUAL ID (container/orchestration) Docker and Kubernetes sometimes show a virtual process ID inside a container, mapped to a different PID on the host. Putting It Together: Real-World Scenarios Scenario A: You see high CPU from a process top -o %CPU # Note the PID (e.g., 9876) ps -p 9876 -o comm= # Result: "ffmpeg" If that ffmpeg is transcoding video, you’ve linked PID (the process) to a VID (video stream ID inside FFmpeg logs). Scenario B: USB device not working dmesg | grep -i usb # Shows "New USB device found, idVendor=2341, idProduct=0043" That’s the PID (Product ID) and VID (Vendor ID). You can then search 2341:0043 to find the driver. Why You Might Have Searched "pid vid" Based on actual search patterns, here’s what people usually want: pid vid

If you’ve ever typed "pid vid" into a search engine, you likely weren’t looking for a new video format. Instead, you were probably deep in a terminal window, trying to debug a process, check a running service, or figure out why a script wasn’t behaving. Let’s break down what these two acronyms mean,
