Summary One of the things that we often encounter when writing programs is to list all the running programs or processes in the system exactly. Windows Task Manager is one of these programs. It lists both the running desktop applications and all the running processes in the system. So, how do we accomplish such a task in a program? This issue is discussed in detail below. Enumerate top level (top-level) W

1. Process five state and state transition diagramFive states: New, ready, run, block, exitThe problems and solutions of the five-state process: When multiple processes compete for resources, it can lead to insufficient memory and the ready queue is full. CPU speed is much faster than IO speed, many processes are in a blocking state, the CPU is idle, the utilization is low. Workaround, program and data (no

Process communication methods and processes Several methods of inter-process communication: 1. Normal pipeline (pipe): pipeline is a standalone communication method. data can only flow in one direction and can only be used between unrelated processes. The kinship of a process usually refers to the relationship between a parent-child process or a sibling process. 2. Stream pipeline (s_pipe): A half-duplex co

Article Title: ensures system security by monitoring processes running in Linux. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems, open source, and other basic categories by using a comprehensive user-level top, ps and other system tools and Linux kernel protection technology, we can comprehensively protect the security of important system

Cause Analysis and nohup usage for disabling background processes on Linux terminal Windows and Linux Remote connections (both called remote connections) are different: 1) after Windows Remote connection, if you run a program on a remote machine, you can log out of the connection and connect to the machine for a while to see if the connection has ended, that is to say, without any processing, the program running on the remote machine will not end with

Kill Kill command: Sends the specified signal to the appropriate process. Do not specify the signal will send Sigterm (15) to terminate the specified process. If you still cannot terminate the program with the "-kill" parameter, it sends a signal of Sigkill (9), which will force the end of the process, using the PS command or the jobs command to view the process number. Root users will affect the user's process, and non-root users can only affect their own
