A daemon is a program that runs as a "background" process (without a terminal or user interface), commonly waiting for events to occur and offering services. A good example is a web server that waits for a request to deliver a page, or a ssh server waiting for someone trying to log in. While these are full featured applications, there are daemons whose work is not that visible. Daemons are for tasks like writing messages into a log file (e.g. syslog, metalog) or keeping your system time accurate (e.g. ntpd). For more information see daemon(7).

In Arch Linux, daemons are managed by systemd. The systemctl command is the user interface used to manage them. It reads name.service files that contain information about how and when to start the associated daemon. Service files are stored in /{etc,usr/lib,run}/systemd/system. See systemd#Using units for details.

List of daemons

Reason: Needlessly duplicates other articles, instead categorize these articles with Category:Daemons, creating redirects if necessary. (Discuss in Talk:Daemons#)

Tango-inaccurate.pngThe factual accuracy of this article or section is disputed.Tango-inaccurate.png

Reason: shadow doesn't appear to be a daemon. (Discuss in Talk:Daemons#)

Here is a list of daemons. Note that any package can provide a daemon, so this list will never be complete. Please feel free to add any missing daemons here, in alphabetical order. You may have packages that include other daemons from the AUR. These files will likely be located in /usr/lib/systemd/system/.

The Package column contains a link to ArchWiki page for each daemon (or link to the package if no such page exists). The initscripts column contains the name of the legacy rc.d script and the systemd column contains the name of the systemd service file. Note that there may be daemons specific to either initscripts or systemd, with the respective column empty. The Description column provides short description, preferably of the daemon (not of the package).
