How am I able to search for duplicate files that are zipped and unzipped, with the same name?

I understand I can do the initial search with the below however, not sure how to pipe in some duplicate file terms...

find / -iname \*.zip

Assuming that you want to find all .zip files in or below the current directory and check whether there's something with the same name but without the .zip filename suffix:

find . -type f -iname '*.zip' -exec sh -c '
    for a do
        n="${a%.zip}"
        [ -e "$n" ] && printf "%s\n" "$n"
    done' sh {} +

With a directory containing

file
file.zip
file2.zip
file3
file3.zip

the above command would output

./file
./file3

This is done by looking for all .zip files, and for all found files run a short shell script that strips the extension off each name in turn and checks whether that new name exists or not.

Alternatively, an slightly shorter,

find . -iname '*.zip' -exec sh -c '[ -e "${0%.zip}" ]' {} ';' -print

This also uses a helper shell script, but it's just testing for the existence of the filename without the .zip suffix. If a suffix-less name exists, the zip file's pathname is outputted.
