# `bitcoin.conf` Configuration File
|
||
|
|
|
||
|
|
The configuration file is used by `bitcoind`, `bitcoin-qt` and `bitcoin-cli`.
|
||
|
|
|
||
|
|
All command-line options (except for `-?`, `-help`, `-version` and `-conf`) may be specified in a configuration file, and all configuration file options (except for `includeconf`) may also be specified on the command line. Command-line options override values set in the configuration file and configuration file options override values set in the GUI.
|
||
|
|
|
||
|
|
## Configuration File Format
|
||
|
|
|
||
|
|
The configuration file is a plain text file and consists of `option=value` entries, one per line. Leading and trailing whitespaces are removed.
|
||
|
|
|
||
|
|
In contrast to the command-line usage:
|
||
|
|
- an option must be specified without leading `-`;
|
||
|
|
- a value of the given option is mandatory; e.g., `testnet=1` (for chain selection options), `noconnect=1` (for negated options).
|
||
|
|
|
||
|
|
### Blank lines
|
||
|
|
|
||
|
|
Blank lines are allowed and ignored by the parser.
|
||
|
|
|
||
|
|
### Comments
|
||
|
|
|
||
|
|
A comment starts with a number sign (`#`) and extends to the end of the line. All comments are ignored by the parser.
|
||
|
|
|
||
|
|
Comments may appear in two ways:
|
||
|
|
- on their own on an otherwise empty line (_preferable_);
|
||
|
|
- after an `option=value` entry.
|
||
|
|
|
||
|
|
### Network specific options
|
||
|
|
|
||
|
|
Network specific options can be:
|
||
|
|
- placed into sections with headers `[main]` (not `[mainnet]`), `[test]` (not `[testnet]`) or `[regtest]`;
|
||
|
|
- prefixed with a chain name; e.g., `regtest.maxmempool=100`.
|
||
|
|
|
||
|
|
## Configuration File Path
|
||
|
|
|
||
|
|
The configuration file is not automatically created; you can create it using your favorite text editor. By default, the configuration file name is `bitcoin.conf` and it is located in the Bitcoin data directory, but both the Bitcoin data directory and the configuration file path may be changed using the `-datadir` and `-conf` command-line options.
|
||
|
|
|
||
|
|
The `includeconf=<file>` option in the `bitcoin.conf` file can be used to include additional configuration files.
