  2. Process identifier - Wikipedia

    en.wikipedia.org/wiki/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 process's priority or ...

  3. procfs - Wikipedia

    en.wikipedia.org/wiki/Procfs

    Linux first added a /proc filesystem in v0.97.3, September 1992, and first began expanding it to non-process related data in v0.98.6, December 1992. As of 2020, the Linux implementation includes a directory for each running process, including kernel processes, in directories named /proc/PID, where PID is the process number. Each directory ...

  4. Linux namespaces - Wikipedia

    en.wikipedia.org/wiki/Linux_namespaces

    Hence, the initial PID namespace is able to see all processes, albeit with different PIDs than other namespaces will see processes with. The first process created in a PID namespace is assigned the process ID number 1 and receives most of the same special treatment as the normal init process, most notably that orphaned processes within the ...

  5. systemd - Wikipedia

    en.wikipedia.org/wiki/Systemd

    systemd tracks processes using the Linux kernel's cgroups subsystem instead of using process identifiers (PIDs); thus, daemons cannot "escape" systemd, not even by double-forking. systemd not only uses cgroups, but also augments them with systemd-nspawn and machinectl , two utility programs that facilitate the creation and management of Linux ...

  6. ps (Unix) - Wikipedia

    en.wikipedia.org/wiki/Ps_(Unix)

    PID: 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 ...

  7. cgroups - Wikipedia

    en.wikipedia.org/wiki/Cgroups

    For example, a PID namespace provides a separate enumeration of process identifiers within each namespace. Also available are mount, user, UTS (Unix Time Sharing), network and SysV IPC namespaces. The PID namespace provides isolation for the allocation of process identifiers (PIDs), lists of processes and their details. While the new namespace ...

  8. Parent process - Wikipedia

    en.wikipedia.org/wiki/Parent_process

    In the Linux kernel, in which there is a very slim difference between processes and POSIX threads, there are two kinds of parent processes, namely real parent and parent. Parent is the process that receives the SIGCHLD signal on child's termination, whereas real parent is the thread that actually created this child process in a multithreaded ...
