Components of some Linuxdesktop environments that are daemons include D-Bus, NetworkManager (here called unetwork), PulseAudio (usound), and Avahi.

In multitasking computer operating systems, a daemon (/ˈdmən/ or /ˈdmən/)[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 for differentiation between a daemon and a normal computer program. For example, syslogd is a daemon that implements system logging facility, and sshd is a daemon that serves incoming SSH connections.

In a Unix environment, the parent process of a daemon is often, but not always, the init process. A daemon is usually created either by a process forking a child process and then immediately exiting, thus causing init to adopt the child process, or by the init process directly launching the daemon. In addition, a daemon launched by forking and exiting typically must perform other operations, such as dissociating the process from any controlling terminal (tty). Such procedures are often implemented in various convenience routines such as daemon(3) in Unix.

No lift no gift mac os. Systems often start daemons at boot time that will respond to network requests, hardware activity, or other programs by performing some task. Daemons such as cron may also perform defined tasks at scheduled times.

Terminology[edit]

The term was coined by the programmers at MIT's Project MAC. They took the name from Maxwell's demon, an imaginary being from a thought experiment that constantly works in the background, sorting molecules.[2]Unix systems inherited this terminology. Maxwell's demon is consistent with Greek mythology's interpretation of a daemon as a supernatural being working in the background, with no particular bias towards good or evil. However, BSD and some of its derivatives have adopted a Christian demon as their mascot rather than a Greek daemon.[citation needed]

The word daemon is an alternative spelling of demon,[3] and is pronounced /ˈdmən/DEE-mən. In the context of computer software, the original pronunciation /ˈdmən/ has drifted to /ˈdmən/DAY-mən for some speakers.[1]

Alternative terms for daemon are service (used in Windows, from Windows NT onwards — and later also in Linux), started task (IBM z/OS),[4] and ghost job (XDS UTS).

After the term was adopted for computer use, it was rationalized as a 'backronym' for Disk And Execution MONitor.[5]

Daemons that connect to a computer network are examples of network services.

Implementations[edit]

Unix-like systems[edit]

In a strictly technical sense, a Unix-like system process is a daemon when its parent process terminates and the daemon is assigned the init process (process number 1) as its parent process and has no controlling terminal. However, more generally, a daemon may be any background process, whether a child of the init process or not.

Hot to compress a file. On a Unix-like system, the common method for a process to become a daemon, when the process is started from the command line or from a startup script such as an init script or a SystemStarter script, involves:

  • Optionally removing unnecessary variables from environment.
  • Executing as a background task by forking and exiting (in the parent 'half' of the fork). This allows daemon's parent (shell or startup process) to receive exit notification and continue its normal execution.
  • Detaching from the invoking session, usually accomplished by a single operation, setsid():
    • Dissociating from the controlling tty.
    • Creating a new session and becoming the session leader of that session.
    • Becoming a process group leader.
  • If the daemon wants to ensure that it will not acquire a new controlling tty even by accident (which happens when a session leader without a controlling tty opens a free tty), it may fork and exit again. This means that it is no longer a session leader in the new session, and cannot acquire a controlling tty.
  • Setting the root directory (/) as the current working directory so that the process does not keep any directory in use that may be on a mounted file system (allowing it to be unmounted).
  • Changing the umask to 0 to allow open(), creat(), and other operating system calls to provide their own permission masks and not to depend on the umask of the caller.
  • Redirecting file descriptors 0, 1 and 2 for the standard streams (stdin, stdout and stderr) to /dev/null or a logfile, and closing all the other file descriptors inherited from the parent process.

If the process is started by a super-server daemon, such as inetd, launchd, or systemd, the super-server daemon will perform those functions for the process,[6][7][8] except for old-style daemons not converted to run under systemd and specified as Type=forking[8] and 'multi-threaded' datagram servers under inetd.[6]

MS-DOS[edit]

In the Microsoft DOS environment, daemon-like programs were implemented as terminate and stay resident (TSR) software.

Windows NT[edit]

Turtlegend And The Spirit Of Shapes Mac Os Download

On Microsoft Windows NT systems, programs called Windows services perform the functions of daemons. They run as processes, usually do not interact with the monitor, keyboard, and mouse, and may be launched by the operating system at boot time. In Windows 2000 and later versions, Windows services are configured and manually started and stopped using the Control Panel, a dedicated control/configuration program, the Service Controller component of the Service Control Manager (sc command), the net start and net stop commands or the PowerShell scripting system.

However, any Windows application can perform the role of a daemon, not just a service, and some Windows daemons have the option of running as a normal process.

Classic Mac OS and macOS[edit]

On the classic Mac OS, optional features and services were provided by files loaded at startup time that patched the operating system; these were known as system extensions and control panels. Later versions of classic Mac OS augmented these with fully fledged faceless background applications: regular applications that ran in the background. To the user, these were still described as regular system extensions.

macOS, which is a Unix system, uses daemons. Note that macOS uses the term 'services' to designate software that performs functions selected from the Services menu, rather than using that term for daemons as Windows does.

Etymology[edit]

Turtlegend And The Spirit Of Shapes Mac Os 11

According to Fernando J. Corbató, who worked on Project MAC in 1963, his team was the first to use the term daemon, inspired by Maxwell's demon, an imaginary agent in physics and thermodynamics that helped to sort molecules, stating, 'We fancifully began to use the word daemon to describe background processes that worked tirelessly to perform system chores'.[9]

In the general sense, daemon is an older form of the word 'demon', from the Greek δαίμων. In the Unix System Administration HandbookEvi Nemeth states the following about daemons:[10]

https://coolofile630.weebly.com/dinocracy-mac-os.html. Many people equate the word 'daemon' with the word 'demon', implying some kind of satanic connection between UNIX and the underworld. https://vrimqtorrent-milkmacmoysenlandos.peatix.com. This is an egregious misunderstanding. 'Daemon' is actually a much older form of 'demon'; daemons have no particular bias towards good or evil, but rather serve to help define a person's character or personality. The ancient Greeks' concept of a 'personal daemon' was similar to the modern concept of a 'guardian angel'—eudaemonia is the state of being helped or protected by a kindly spirit. As a rule, UNIX systems seem to be infested with both daemons and demons.

A further characterization of the mythological symbolism is that a daemon is something that is not visible yet is always present and working its will. In the Theages, attributed to Plato, Socrates describes his own personal daemon to be something like the modern concept of a moral conscience: 'The favour of the gods has given me a marvelous gift, which has never left me since my childhood. It is a voice that, when it makes itself heard, deters me from what I am about to do and never urges me on'.[citation needed]
