Introduction In the world of Linux, processes play a crucial role in enabling software programs to function efficiently. Each running application or task on a computer system is assigned a distinct process identification number (PID) that serves as a unique identifier to differentiate it from any other active process running on the same system. Similarly, every network connection in a computer system is associated with a specific port number that helps identify the source and destination of the data transfer. In some cases, it may be necessary to find the PID of a process that is using a particular port. ... Read More
