# Name

`nix daemon` - daemon to perform store operations on behalf of non-root clients

# Synopsis

`nix daemon` [option...]

# Examples

- Run the daemon:

      # nix daemon

- Run the daemon and listen on standard I/O instead of binding to a UNIX socket:

      # nix daemon --stdio

- Run the daemon and force all connections to be trusted:

      # nix daemon --force-trusted

- Run the daemon and force all connections to be untrusted:

      # nix daemon --force-untrusted

- Run the daemon, listen on standard I/O, and force all connections to use Nix's default trust:

      # nix daemon --stdio --default-trust

# Description

This command runs the Nix daemon, which is a required component in multi-user Nix installations. It runs build tasks and other operations on the Nix store on behalf of non-root users. Usually you don't run the daemon directly; instead it's managed by a service management framework such as `systemd` on Linux, or `launchctl` on Darwin.

Note that this daemon does not fork into the background.

# Options

- `--default-trust` Use Nix's default trust.

- `--force-trusted` Force the daemon to trust connecting clients.

- `--force-untrusted` Force the daemon to not trust connecting clients. The connection will be processed by the receiving daemon before forwarding commands.

- `--stdio` Attach to standard I/O, instead of trying to bind to a UNIX socket.

Logging-related options:

- `--debug` Set the logging verbosity level to 'debug'.

- `--print-build-logs` / `-L` Print full build logs on standard error.

- `--quiet` Decrease the logging verbosity level.

- `--verbose` / `-v` Increase the logging verbosity level.

Miscellaneous global options:

- `--help` Show usage information.

- `--offline` Disable substituters and consider all previously downloaded files up-to-date.

- `--option` name value Set the Lix configuration setting name to value (overriding `nix.conf`).

- `--refresh` Consider all previously downloaded files out-of-date.

- `--version` Show version information.

> Note

> See `man nix.conf` for overriding configuration settings with command line flags.
