Find, count , hash, and scan all executables on the local drive: how to?

Hi to all,

I'd like to find, count, hash, an scan with clamav all the executable on my pc.

I've seen that I can list all of them by using the following command:

sudo find / \( -path "pathToExclude1" -o -path "pathToExclude2" -o -path "pathToExclude3" -o -path "pathToExclude4" \) -prune -o -type f -perm -u+x -ls

Now instead of listing them I'd like to

1. count them

2. hash them with sha256 and store path and hash code in a file

3. scan them with clamav passing the list of file

Is there any how to to help me in writing this bash script?
