Command Line Options

Running BiglyBT from the command line

Windows

Start a 'command prompt' by searching for and running 'cmd.exe'.

Change directory into wherever you have installed BiglyBT, usually

cd "C:\Program Files\BiglyBT"

or

cd "C:\Program Files (x86)\BiglyBT"

Type in the following to try and run BiglyBT:

java -cp "BiglyBT.jar;commons-cli.jar;swt.jar" com.biglybt.ui.Main

If that reports an error regarding finding java then see if you have a Java runtime installed in either C:\Program Files\Java or C:\Program Files (x86)\Java, for example C:\Program Files\Java\jre1.8.0_231

If so then replace 'java' with a full path, in this example

"C:\Program Files\Java\jre1.8.0_231"\bin\java -cp "BiglyBT.jar;commons-cli.jar;swt.jar" com.biglybt.ui.Main

If you can't find a Java installation then you can go to http://java.com/ and install Java. Then repeat the above steps to locate the runtime and set the correct path.

Once you have that working you can save the command line into a batch file, say run.bat, and use that to start BiglyBT.

System Properties

System Properties are set by using the -D<name>=<value> JVM command line parameters. You can use 'biglybt.' in place of 'azureus.' in property names.

Some of the more useful ones are

• azureus.config.path: string - folder where BiglyBT configuration data is stored
• azureus.instance.port: integer - port used to communicate between instances
• MULTI_INSTANCE: boolean - allows multiple instances of BiglyBT to run when set to true

Running Multiple BiglyBT Instances

On Windows copy everything from wherever BiglyBT is installed (e.g. C:\Program Files\BiglyBT) into a separate folder - say "C:\BiglyBT2"

Then create a .bat file in this folder (say run.bat) with contents

java -cp "BiglyBT.jar;commons-cli.jar;swt.jar" -Djava.library.path=C:\BiglyBT2 -Duser.dir=C:\BiglyBT2 -Dazureus.config.path=C:\BiglyBT2 -DMULTI_INSTANCE=true com.biglybt.ui.Main

and run this.
