Delete a case insensitive filename from a .zip file

I’ve got thousands of .zip files in subdirectories with a few different errant images in them we’ll call crap.*. But they’re different cases in the filenames. The files could have different extensions and some additional character in front of or behind the crap, such as 123crap567.jpg or -crap-.gif.

I’m trying to write a bash script for Linux to scan through the directories, find the zip’s with the CrAp.PNG, and delete that file from within the zip. Below is my code I’ve got so far, but it’s not working.

I believe I’m scanning through and finding the correct zip files, and identifying the exact name of the “crap files”. But I’m getting:

zip error: Invalid command arguments (specify just one action)

What am I doing wrong?

for i in *.zip; do
    [ -f "$i" ] || break
    f=$(zipinfo "$i" | grep -i -ho "S*crapS*")
    if [[ $f ]]; then
      zipinfo "$i" | grep -i -ho "S*crapS*" | xargs zip -d '*/$i'
    fi
done
