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.
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 ...
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 ...
The kill command is a wrapper around the kill() system call, which sends signals to processes or process groups on the system, referenced by their numeric process IDs (PIDs) or process group IDs (PGIDs). kill is always provided as a standalone utility as defined by the POSIX standard. However, most shells have built-in kill commands that may ...
lsof. lsof is a command meaning "list open files", which is used in many Unix-like systems to report a list of all open files and the processes that opened them. This open source utility was developed and supported by Victor A. Abell, the retired Associate Director of the Purdue University Computing Center.
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.
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.
Svchost.exe (Service Host, or SvcHost) is a system process that can host one or more Windows services in the Windows NT family of operating systems. [1] Svchost is essential in the implementation of shared service processes, where a number of services can share a process in order to reduce resource consumption.
