How to check if find command didn't find anything?

Question

I know that is possible to use for loop with find command like that

for i in `find $something`; do (...) done

but I want to use find comma

Iterating over the output of find might be dangerous if your filenames contain spaces. If you're sure they don't, you can store the result of find to an array, and check its size to see there were any hits:

results=( $(find -name "$something") )
if (( ${#results[@]} )) ; then
    echo Found
else
    echo Not found
fi
for file in "${results[@]}" ; do
   # ...
done
