NetBSD find supports this as -exit [N] (https://man.netbsd.org/find.1)

The difference with -quit is that -exit suppresses the default -print, which is often what you want if you're just checking the exit code.

A very typical use case for find in shell scripting is to check if some files exist, e.g. in an if block:

if find /tmp -name 'some_pattern*' | grep -q .
then
  do_something
fi

Unfortunately find currently doesn't have any way to communicate "some matches" or "no matches" via exit code, necessitating the grep -q workaround, or another workaround like -exec false:

if find /tmp -name 'some_pattern*' -exec false {} +
then
  do_something
fi

There is a -quit operator that exits find immediately, but it doesn't currently support specifying an exit code. It would be useful if it were possible to specify an exit code via -quit N so we could use find like this:

if ! find /tmp -name 'some_pattern*' -quit 1
then
  do_something
fi

Adding support for specifying an exit code has been suggested by berny before, but unfortunately it went unnoticed: https://savannah.gnu.org/bugs/?func=detailitem&item_id=54730#comment6
