Options for bucardo can be specified either at the command line or inside configuration files. There are three files that are checked in order, and the first one that is found is used:

• .bucardorc in the current directory
• .bucardorc in the user’s home directory
• /etc/bucardorc

The format of each file is simply name=value, where name is any of the options passed to the bucardo program. Any command line options will override the options in the bucardorc file.

If the option --no-bucardorc is given to bucardo, none of the bucardorc files will be used.

You can also specify the location of a bucardorc file to use, by using --bucardorc=filename. If this option is used, all other default locations above will be ignored, and the program will abort if the file is not found.
