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 process's priority or ...
It has since been available in illumos and reimplemented for the Linux and BSDs (DragonFly BSD, FreeBSD, NetBSD, and OpenBSD). It searches for all the named processes that can be specified as extended regular expression patterns, and—by default—returns their process ID. Alternatives include pidof (finds process ID given a program name) and ps.
pstree is a Linux command that shows the running processes as a tree [1] [2] [3]. It is used as a more visual alternative to the ps command. The root of the tree is either init or the process with the given pid. It can also be installed in other Unix systems. In BSD systems, a similar output is created using ps -d, in Linux ps axjf [4] produces ...
Process ID number PPID: ID number of the process's parent process PRI: Priority of the process RSS: Resident set size: S or STAT: Process status code START or STIME: Time when the process started VSZ: Virtual memory usage TIME: The amount of CPU time used by the process TT or TTY: Terminal associated with the process UID or USER: Username of ...
The term "namespace" is often used to denote a specific type of namespace (e.g., process ID) as well as for a particular space of names. [1] A Linux system begins with a single namespace of each type, used by all processes. Processes can create additional namespaces and can also join different namespaces.
In Unix-like operating systems, every process except process 0 (the swapper) is created when another process executes the fork() system call. The process that invoked fork is the parent process and the newly created process is the child process. Every process (except process 0) has one parent process, but can have many child processes.

systemd, a software suite, full replacement for init in Linux that includes an init daemon, with concurrent starting of services, service manager, and other features. SystemStarter, a process spawner started by the BSD-style init in Mac OS X prior to Mac OS X v10.4; Upstart, a full replacement of init designed to start processes asynchronously.
