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

Synopsis
       nix store ping [option<?>]

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

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

       o  Test whether a URL is a valid binary cache:

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

       o  Test whether the Nix daemon is up and running:

       # nix store info --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 Nix
       can connect to the specified machine.

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

Options
       o  --json

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

   Logging-related options
       o  --debug

          Set the logging verbosity level to `debug'.

       o  --log-format format

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

       o  --print-build-logs / -L

          Print full build logs on standard error.

       o  --quiet

          Decrease the logging verbosity level.

       o  --verbose / -v

          Increase the logging verbosity level.

   Miscellaneous global options
       o  --help

          Show usage information.

       o  --offline

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

       o  --option name value

          Set the Nix configuration setting name to value (overriding
          nix.conf).

       o  --refresh

          Consider all previously downloaded files out-of-date.

       o  --version
