var commandDefinition = &cobra.Command{
Use: "copyurl https://example.com dest:path",
Short: `Copy the contents of the URL supplied content to dest:path.`,
Long: strings.ReplaceAll(`
Download a URL's content and copy it to the destination without saving
it in temporary storage.
Setting |--auto-filename| will attempt to automatically determine the
filename from the URL (after any redirections) and used in the
destination path.
With |--auto-filename-header| in addition, if a specific filename is
set in HTTP headers, it will be used instead of the name from the URL.
With |--print-filename| in addition, the resulting file name will be
printed.
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.
### Troublshooting
If you can't get |rclone copyurl| to work then here are some things you can try:
- |--disable-http2| rclone will use HTTP2 if available - try disabling it
- |--bind 0.0.0.0| rclone will use IPv6 if available - try disabling it
- |--bind ::0| to disable IPv4
- |--user agent curl| - some sites have whitelists for curl's user-agent - try that
- Make sure the site works with |curl| directly
