Use: "copyurl https://example.com dest:path",
Short: `Copy url content to dest.`,
Long: `
Download a URL's content and copy it to the destination without saving
it in temporary storage.
Setting --auto-filename will cause the file name to be retrieved from
the from URL (after any redirections) and used in the destination
path.
Setting --no-clobber will prevent overwriting file on the
destination if there is one with the same name.
Setting --stdout or making the output file name "-" will cause the
output to be written to standard output.
