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 info --store ssh://mac1

Test whether a URL is a valid binary cache:

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

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

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