I expect btt could report data, but it did not.

  • did you check `man btt` or `btt --help` (etc)? Stackoverflow is dedicated to helping solve `if/then/else` programming problems. Your question may be more suitable for [su] or [unix.se], but please read their help sections concerning "how-to-ask" and on-topic questions. Good luck. – shellter Aug 02 '23 at 15:43
