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.

       •  --process-ops

          Forces  the daemon to process received commands itself rather than forwarding the commands straight to
          the remote store.

             This is useful for the `mounted-ssh://` store where some actions need to be performed on the remote end but as connected user, and not as the user of the underlying daemon on the remote end.

       •  --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’.

       •  --log-format format

          Set the format of log output; one of raw, internal-json, bar or bar-with-logs.

       •  --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 Nix 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.
