Unix, Unix-like, Plan 9, Inferno, KolibriOS, IBM i. Platform. Cross-platform. Type. Command. License. Plan 9: MIT License. In most Unix and Unix-like operating systems, the ps (process status) program displays the currently-running processes. The related Unix utility top provides a real-time view of the running processes.
Process identifier. In computing, the process identifier (a.k.a. process ID or PID) is a number used by most operating system kernels —such as those of Unix, macOS and Windows —to uniquely identify an active process. This number may be used as a parameter in various function calls, allowing processes to be manipulated, such as adjusting the ...
netstat. In computing, netstat (network statistics) is a command-line network utility that displays network connections for Transmission Control Protocol (both incoming and outgoing), routing tables, and a number of network interface (network interface controller or software-defined network interface) and network protocol statistics.
Type. Command. In computing, tasklist is a command available in Microsoft Windows [1] and in the AROS shell. [2] It is equivalent to the ps command in Unix and Unix-like operating systems and can also be compared with the Windows task manager (taskmgr). Windows NT 4.0, the Windows 98 Resource Kit, the Windows 2000 Support Tools, and ReactOS [3 ...
ProcDump. ProcDump is a command-line application used for monitoring an application for CPU spikes and creating crash dumps during a spike. [2][3] The crash dumps can then be used by an administrator or software developer to determine the cause of the spike. ProcDump supports monitoring of hung windows and unhandled exceptions.
In multitasking computer operating systems, a daemon (/ ˈdiːmən / or / ˈdeɪmən /) [1] is a computer program that runs as a background process, rather than being under the direct control of an interactive user. Traditionally, the process names of a daemon end with the letter d, for clarification that the process is in fact a daemon, and ...
Proportional–integral–derivative controller. A proportional–integral–derivative controller (PID controller or three-term controller) is a feedback -based Control loop mechanism commonly used in industrial control systems and various other applications requiring continuously modulated control. A PID controller continuously calculates an ...
Named pipe. In computing, a named pipe (also known as a FIFO for its behavior) is an extension to the traditional pipe concept on Unix and Unix-like systems, and is one of the methods of inter-process communication (IPC). The concept is also found in OS/2 and Microsoft Windows, although the semantics differ substantially.
