Display version information for the balena CLI and/or Node.js.
|
|
|
|
Display version information for the balena CLI and/or Node.js. Note that the
|
|
balena CLI executable installers for Windows and macOS, and the standalone
|
|
zip packages, ship with a built-in copy of Node.js. In this case, the
|
|
reported version of Node.js regards this built-in copy, rather than any
|
|
other \`node\` engine that may also be available on the command prompt.
|
|
|
|
The --json option is recommended when scripting the output of this command,
|
|
because the JSON format is less likely to change and it better represents
|
|
data types like lists and empty strings. The 'jq' utility may be helpful
|
|
in shell scripts (https://stedolan.github.io/jq/manual/).
|
|
|
|
This command can also be invoked with 'balena --version' or 'balena -v'.
