Q: What is a PID in Linux? A: PID stands for Process ID, a unique identifier assigned to each process running on a Unix-based system. This identifier allows users and programs to manage running processes, such as sending signals or checking the status of a process. Q: Why might I want to capture a PID of a background process launched via a pipeline? A: Knowing a background process's PID can be crucial for monitoring its progress, managing resource allocation, or gracefully stopping the process without affecting other system operations.

When working in a Linux environment, efficiency and real-time feedback are crucial, especially when handling large volumes of data. Whether you are transferring large files, compressing data, or streaming data between processes, knowing how fast the data is moving and how much time it might take to complete can be incredibly valuable. This is where the utility pv (Pipe Viewer) becomes an indispensable tool in your Linux toolkit. In this blog post, we'll dive into what pv is, why you should use it, and how to install and utilize it across different Linux distributions. pv stands for Pipe Viewer, a terminal-based tool in Unix-like systems that allows you to monitor the progress of data through a pipeline.
