--help => Show this usage information.
--cachedir => Directory for Lyrion Music Server to save cached music and web data
--tmpdir => Directory for Lyrion Music Server's temporary files (cleaned on start and stop)
--diag => Use diagnostics, shows more verbose errors.
Also slows down library processing considerably
--logdir => Specify folder location for log file
--logfile => Specify a file for error logging. Specify 'syslog' to log to syslog.
--daemon => Run the server in the background.
This may only work on Unix-like systems.
--stdio => Use standard in and out as a command line interface
to the server
--user => Specify the user that server should run as.
Only usable if server is started as root.
This may only work on Unix-like systems.
--group => Specify the group that server should run as.
Only usable if server is started as root.
This may only work on Unix-like systems.
--httpport => Activate the web interface on the specified port.
Set to 0 in order disable the web server.
--httpaddr => Activate the web interface on the specified IP address.
--advertiseaddr => IP address to report as its exposed address. Basically the user facing IP address.
--cliport => Activate the command line interface TCP/IP interface
on the specified port. Set to 0 in order disable the
command line interface server.
--cliaddr => Activate the command line interface TCP/IP
interface on the specified IP address.
--prefsdir => Specify the location of the preferences directory
--pidfile => Specify where a process ID file should be stored
--quiet => Minimize the amount of text output
--playeraddr => Specify the _server's_ IP address to use to connect
to Slim players
--priority => set process priority from -20 (high) to 20 (low)
--streamaddr => Specify the _server's_ IP address to use to connect
to streaming audio sources
--nodebuglog => Disable all debug-level logging (compiled out).
--noinfolog => Disable all debug-level & info-level logging (compiled out).
--norestart => Disable automatic restarts of server (if performed by external script)
--nosetup => Disable setup via http.
--noserver => Disable web access server settings, but leave player settings accessible.
Settings changes are not preserved.
--noweb => Disable web interface. JSON-RPC, Comet, and artwork web APIs are still enabled.
--nosb1slimp3sync=> Disable support for SliMP3s, SB1s and associated synchronization
--nostatistics => Disable the TracksPersistent table used to keep to statistics across rescans (compiled out).
--notranscoding => Disable transcoding support.
--nobrowsecache => Disable caching of rendered browse pages.
--perfmon => Enable internal server performance monitoring
--perfwarn => Generate log messages if internal tasks take longer than specified threshold
--failsafe => Don't load plugins
--checkstrings => Enable reloading of changed string files for plugin development
--charset => Force a character set to be used, eg. utf8 on Linux devices
which don't have full utf8 locale installed
--dbtype => Force database type (valid values are MySQL or SQLite)
--logging => Enable logging for the specified comma separated categories
--localfile => Enable LocalFile protocol handling for locally connected squeezelite service
Commands may be sent to the server through standard in and will be echoed via
standard out. See complete documentation for details on the command syntax.
