Usage: /usr/local/bin/Orthanc [OPTION]... [CONFIGURATION] Orthanc, lightweight, RESTful DICOM server for healthcare and medical research. The "CONFIGURATION" argument can be a list of files or directories. In the case of a directory, all the JSON files it contains will be merged. If no configuration path is given on the command line, a set of default parameters is used. Please refer to the Orthanc Book for the full instructions about how to use Orthanc . Pay attention to the fact that the order of the options is important. Options are read left to right. In particular, options such as "--verbose" can reset the value of other log-related options that were read before. The recommended set of options to debug DICOM communications is "--verbose --trace-dicom --logfile=dicom.log" Generic options: --help display this help and exit --version output version information and exit --config file create a sample configuration file and exit (if "file" is "-", dumps to stdout) --advanced-config file create a file containing the advanced configuration options and exit (if "file" is "-", dumps to stdout) --errors print the supported error codes and exit --upgrade allow Orthanc to upgrade the version of the database (beware that the database will become incompatible with former versions of Orthanc) --no-jobs don't restart the jobs that were stored during the last execution of Orthanc --openapi file write the OpenAPI documentation and exit (if "file" is "-", dumps to stdout) --cheatsheet file write the cheat sheet of REST API as CSV and exit (if "file" is "-", dumps to stdout) Logging options: --logdir dir directory where to store the log files (by default, the log is dumped to stderr) --logfile file file where to store the log of Orthanc (by default, the log is dumped to stderr) --verbose be verbose in logs --trace highest verbosity in logs (for debug) --logs-no-thread remove thread names from logs --logs-no-context remove contexts from logs --logs-thread-names-in-context include caller thread names in log contexts Fine-tuning of log categories: --verbose-generic be verbose in logs of category "generic" --trace-generic use highest verbosity for logs of category "generic" --verbose-plugins be verbose in logs of category "plugins" --trace-plugins use highest verbosity for logs of category "plugins" --verbose-http be verbose in logs of category "http" --trace-http use highest verbosity for logs of category "http" --verbose-sqlite be verbose in logs of category "sqlite" --trace-sqlite use highest verbosity for logs of category "sqlite" --verbose-dicom be verbose in logs of category "dicom" --trace-dicom use highest verbosity for logs of category "dicom" --verbose-jobs be verbose in logs of category "jobs" --trace-jobs use highest verbosity for logs of category "jobs" --verbose-lua be verbose in logs of category "lua" --trace-lua use highest verbosity for logs of category "lua" Exit status: 0 if success, -1 if error (have a look at the logs).
