# Name

`nix store ping` - test whether a store can be accessed

# Synopsis

`nix store ping` [option...]

# Examples

- Test whether connecting to a remote Nix store via SSH works:

      # nix store ping --store ssh://mac1

- Test whether a URL is a valid binary cache:

      # nix store ping --store https://cache.nixos.org

- Test whether the Nix daemon is up and running:

      # nix store ping --store daemon

# Description

This command tests whether a particular Nix store (specified by the argument `--store` url) can be accessed. What this means is dependent on the type of the store. For instance, for an SSH store it means that Lix can connect to the specified machine.

If the command succeeds, Lix returns a exit code of 0 and does not print any output.

# Options

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

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- `--refresh` Consider all previously downloaded files out-of-date.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