Use: "size remote:path",
Short: `Prints the total size and number of objects in remote:path.`,
Long: `
Counts objects in the path and calculates the total size. Prints the
result to standard output.
By default the output is in human-readable format, but shows values in
both human-readable format as well as the raw numbers (global option
` + "`--human-readable`" + ` is not considered). Use option ` + "`--json`" + `
to format output as JSON instead.
Recurses by default, use ` + "`--max-depth 1`" + ` to stop the
recursion.
Some backends do not always provide file sizes, see for example
[Google Photos](/googlephotos/#size) and
[Google Drive](/drive/#limitations-of-google-docs).
Rclone will then show a notice in the log indicating how many such
files were encountered, and count them in as empty files in the output
of the size command.
