feature request: quiet output

[3ricj]

feature request:

--quiet -q suppress all messages except for critical errors

It's a lovely app which is working well, but boy it's chatty while doing it's work.

Best, -3ric

frankly, the json output #124 would work for me as well. It would mostly be nice to know if there was an error or not in the case of scripting this tool -- the current output is complex to parse.

What exactly do you expect this new option to do? If you want to simply print nothing, you can already just redirect output to /dev/null, e.g.

uhubctl ... > /dev/null

If new -q option is enabled, I can't just completely avoid any printing to stdout, can I?

Regarding json output (not even talking that it's not trivial effort in it's own right), I would expect it will print even more text overall because output json most likely to have a lot more data in it than current output does.

As with many unix utilities, include classics like rsync and grep, there are options for verbosity and quiet. Normally verbose (-v or -vv) provides additional details of what's going on -- helpful for debugging a problem.

-q is common when "normal" output isn't needed, but you may want to see errors or exceptions. I'm unsure if your app actually reports errors on stderr or stdout -- if errors are sent on stderr then redirection of stdout works great as a workaround.

Effectively: -q would be helpful if it only told me about problems. If everything is great, then great, I don't need to see any output. Much like I don't need a lightswitch that talks. I mentioned json because I could filter out signals from noise much easier.

Current, this is spewing into my logs.. which... is lovely but ...
