I'm glad he mentioned the "Silence trumps noise" point. I like to call the idiom "no news is good news". Tell me only when I need to know something (like a failure); "-v" is always there if I need it. It feels uncomfortable to get no output at first, but once you get used to it there's much less to read.

It's rather like the Plan 9 convention of programs returning strings instead of ints when then terminate; an empty string means success, a non-empty string contains the error message. I wish other OSes had adopted that.

There is no silence vs noise problem. Send output to STDOUT and "noise" to STDERR. Use -q and -v when appropriate. I thought it was weird that the author created a false dichotomy between being informational and giving only output that can be easily processed.
Problem with "silence" and "no news" is they are indistinguishable from many failure modes.

I vastly prefer confirmation of action(s) as default and -q flag. At very lest there needs to be -v flag that provides confirmation of action(s)

Configure your shell to report nonzero exit statuses.

  joey@gnu:~>true
  joey@gnu:~>false
  zsh: exit 1
In zsh this is done by "setopt print_exit_value". It's a pity shells don't do it by default.
Good hint, but it's value is very niche. Waiting until exit for status is fail. Many commands take seconds if not minutes/hours to complete. I wanna see some indication that they are working and not hung/etc.
