# cupsd(8)

## Name

cupsd - cups scheduler

## Synopsis

cupsd [ -c cupsd.conf ] [ -f ] [ -F ] [ -h ] [ -l ] [ -s cups-files.conf ] [ -t ]

## Description

cupsd is the scheduler for CUPS. It implements a printing system based upon the Internet Printing Protocol, version 2.1, and supports most of the requirements for IPP Everywhere. If no options are specified on the command-line then the default configuration file /etc/cups/cupsd.conf will be used.

## Options

-c cupsd.conf
  Uses the named cupsd.conf configuration file.
-f
  Run cupsd in the foreground; the default is to run in the background as a "daemon".
-F
  Run cupsd in the foreground but detach the process from the controlling terminal and current directory. This is useful for running cupsd from init(8).
-h
  Shows the program usage.
-l
  This option is passed to cupsd when it is run from launchd(8) or systemd(8).
-s cups-files.conf
  Uses the named cups-files.conf configuration file.
-t
  Test the configuration file for syntax errors.
