cupsd: [t]est the [`c`]`upsd.conf` configuration file for errors.
$ cupsd -t -c ${path-to-cupsd-conf}
try on your machine

The command cupsd -t -c ${path-to-cupsd-conf} is used to test the configuration file of the Common Unix Printing System (CUPS) daemon.

Here is the breakdown of the command:

  • cupsd: It is the command to start the CUPS daemon, which is the core service responsible for managing print jobs and printer queues on a Unix-like system.
  • -t: This option tells the cupsd command to perform a configuration syntax check and verifies that the configuration file is free from errors.
  • -c ${path-to-cupsd-conf}: This option specifies the path to the cupsd.conf file, which contains the configuration settings for the CUPS daemon. By providing the path to this file, you are indicating that the daemon should use this particular configuration file for the test.

Overall, the cupsd -t -c ${path-to-cupsd-conf} command is used to check the validity of the CUPS daemon's configuration file, ensuring that it is correctly written and doesn't contain any syntax errors.
