Name

nix store info - test whether a store can be accessed

Synopsis

nix store info [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.

--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.

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

--option name value

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

--refresh
