# [DESCRIPTION](#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](#OPTIONS)

[**-c cupsd.conf**](#c)

Uses the named cupsd.conf configuration file.

[**-f**](#f)

Run **cupsd** in the foreground; the default is to run in the background as a "daemon".

[**-F**](#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)](/man/os/cups/init.8).

[**-h**](#h)

Shows the program usage.

[**-l**](#l)

This option is passed to **cupsd** when it is run from [**launchd**(8)](/man/os/cups/launchd.8) or [**systemd**(8)](/man/os/cups/systemd.8).

[**-s cups-files.conf**](#s)

Uses the named cups-files.conf configuration file.

[**-t**](#t)

Test the configuration file for syntax errors.
