Description

This command lists all currently running Nix builds. For each build, it shows the derivation path and the main process ID. On Linux and macOS, it also shows the child processes of each build.

Options

  • --json

    Produce output in JSON format, suitable for consumption by another program.

  • --no-pretty

    Print compact JSON output on a single line, even when the output is a terminal. Some commands may print multiple JSON objects on separate lines.

                  See `--pretty`.

  • --pretty

    Print multi-line, indented JSON output for readability.

                  Default: indent if output is to a terminal.

              This option is only effective when `--json` is also specified.

  • --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    Consider all previously downloaded files out-of-date.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.
