This means the creation, modification or deletion of files on one machine will automatically be replicated to your other devices. We believe your data is your data alone and you deserve to choose where it is stored. Therefore Syncthing does not upload your data to the cloud but exchanges your data across your machines as soon as they are online at the same time. .SH OPTIONS .INDENT 0.0 .TP .B \-audit Write events to audit file. .UNINDENT .INDENT 0.0 .TP .B \-generate= Generate key and config in specified dir, then exit. .UNINDENT .INDENT 0.0 .TP .B \-gui\-address=
Override GUI address. .UNINDENT .INDENT 0.0 .TP .B \-home= Set configuration directory. The default configuration directory is: \fB$HOME/.config/syncthing\fP\&. .UNINDENT .INDENT 0.0 .TP .B \-logfile= Set destination filename for logging (use \fB"\-"\fP for stdout, which is the default option). .UNINDENT .INDENT 0.0 .TP .B \-logflags= Select information in log line prefix, default 2. The \fB\-logflags\fP value is a sum of the following: .INDENT 7.0 .IP \(bu 2 1: Date .IP \(bu 2 2: Time .IP \(bu 2 4: Microsecond time .IP \(bu 2 8: Long filename .IP \(bu 2 16: Short filename .UNINDENT .sp To prefix each log line with date and time, set \fB\-logflags=3\fP (1 + 2 from above). The value 0 is used to disable all of the above. The default is to show time only (2). .UNINDENT .INDENT 0.0 .TP .B \-no\-browser Do not start a browser. .UNINDENT .INDENT 0.0 .TP .B \-no\-console Hide the console window. (On Windows only) .UNINDENT .INDENT 0.0 .TP .B \-no\-restart Do not restart; just exit. .UNINDENT .INDENT 0.0 .TP .B \-paths Print the paths used for configuration, keys, database, GUI overrides, default sync folder and the log file. .UNINDENT .INDENT 0.0 .TP .B \-reset Reset the database. .UNINDENT .INDENT 0.0 .TP .B \-upgrade Perform upgrade. .UNINDENT .INDENT 0.0 .TP .B \-upgrade\-check Check for available upgrade. .UNINDENT .INDENT 0.0 .TP .B \-upgrade\-to= Force upgrade directly from specified URL. .UNINDENT .INDENT 0.0 .TP .B \-verbose Print verbose log output. .UNINDENT .INDENT 0.0 .TP .B \-version Show version. .UNINDENT .SH DEPRECATED OPTIONS .INDENT 0.0 .TP .B \-gui\-apikey= Override GUI API key (deprecated as of v0.13, to be removed in the future \- do not use). .UNINDENT .SH EXIT CODES .INDENT 0.0 .TP .B 0 Success / Shutdown .TP .B 1 Error .TP .B 2 Upgrade not available .TP .B 3 Restarting .TP .B 4 Upgrading .UNINDENT .sp Some of these exit codes are only returned when running without a monitor process (with environment variable \fBSTNORESTART\fP set). Exit codes over 125 are usually returned by the shell/binary loader/default signal handler. Exit codes over 128+N on Unix usually represent the signal which caused the process to exit. For example, \fB128 + 9 (SIGKILL) = 137\fP\&. .SH DEVELOPMENT SETTINGS .sp The following environment variables modify Syncthing\(aqs behavior in ways that are mostly useful for developers. Use with care. If you start syncthing from within service managers like systemd or supervisor path expansion may not be supported. .INDENT 0.0 .TP .B STNODEFAULTFOLDER Don\(aqt create a default folder when starting for the first time. This variable will be ignored anytime after the first run. .TP .B STGUIASSETS Directory to load GUI assets from. Overrides compiled in assets. .TP .B STTRACE A comma separated string of facilities to trace. The valid facility strings are: .INDENT 7.0 .TP .B beacon the beacon package .TP .B discover the discover package .TP .B events the events package .TP .B files the files package .TP .B http the main package; HTTP requests .TP .B locks the sync package; trace long held locks .TP .B net the main package; connections & network messages .TP .B model the model package .TP .B scanner the scanner package .TP .B stats the stats package .TP .B upnp the upnp package .TP .B xdr the xdr package .TP .B all all of the above .UNINDENT .TP .B STPROFILER Set to a listen address such as "127.0.0.1:9090" to start the profiler with HTTP access. .TP .B STCPUPROFILE Write a CPU profile to cpu\-$pid.pprof on exit. .TP .B STHEAPPROFILE Write heap profiles to \fBheap\-$pid\-$timestamp.pprof\fP each time heap usage increases. .TP .B STBLOCKPROFILE Write block profiles to \fBblock\-$pid\-$timestamp.pprof\fP every 20 seconds. .TP .B STPERFSTATS Write running performance statistics to \fBperf\-$pid.csv\fP\&. Not supported on Windows. .TP .B STNOUPGRADE Disable automatic upgrades. .TP .B GOMAXPROCS Set the maximum number of CPU cores to use. Defaults to all available CPU cores. .TP .B GOGC Percentage of heap growth at which to trigger GC. Default is 100. Lower numbers keep peak memory usage down, at the price of CPU usage (ie. performance). .UNINDENT .SH SEE ALSO .sp \fIsyncthing\-config(5)\fP, \fIsyncthing\-stignore(5)\fP, \fIsyncthing\-device\-ids(7)\fP, \fIsyncthing\-security(7)\fP, \fIsyncthing\-networking(7)\fP, \fIsyncthing\-versioning(7)\fP, \fIsyncthing\-faq(7)\fP .SH AUTHOR The Syncthing Authors .SH COPYRIGHT 2015, The Syncthing Authors .\" Generated by docutils manpage writer. .
