Feature request: Option to suppress normal output

[fearphage]

Please describe your feature request.

I quite often want to confirm the existence or absence of certain data in a file. For that purpse, I use yq --exit-status to convey that information. When using that flag, it is most commonly the only output I require. So I end up writing yq --exit-status ... &> /dev/null to throw away the extraneous output. It would be convenient if I didn't have to work around the unwanted output from the CLI and I could explicitly suppress it instead.

Just as an example:

function contains-key {
  yq --exit-status "$1" "$2" &> /dev/null
}

if contains-key '.catpants' 'my/file.txt'; then
  # do the needful
fi

Describe the solution you'd like

I'd like to see a new flag that doesn't require work arounds to keep the console/output clean.

A few implementation thoughts:

Additional flags to be combined with --exit-status:

• --quiet
• --silent
• --suppress-output - a bit more verbose but very explicit

A different approach - an alternate (replacement?) flag:

• --exit-status-only
  This could theoretically allow you to deprecate --exit-status in favor of this one. I'm honestly not sure if people are using both outputs at once. Or it could simply be remain a nice alternative.

Additional context

With this option, there'd be no need to pipe output to /dev/null. For reference, this is similar to the grep option:

✗ grep --help | grep quiet
  -q, --quiet, --silent     suppress all normal output
