You should be able to read the output of that command with [1]. Make sure that you use the --file option before your output file name. I tried the command you ran and didn't get any output because I didn't have --file before the output name. Maybe a version difference?
By default it seems that the rx_samples_to_file saves samples as SC16 (short complex 16 bit). I had assumed it would be FC32 which would require the use of [2] to read. You can change the output format (CPU format) with the --type option. Check the output of --help to see the type options.
