I want to delete all files which have names containing a specific word, e.g. \"car\". So far, I came up with this:
find|grep car
How do I pass
A bit of necromancy, but you can also use find, grep, and xargs
find . -type f | grep -e "pattern1" -e "pattern2" | xargs rm -rf
^ Find will need some attention to make it work for your needs potentially, such as is a file, mindepth, maxdepth and any globbing.
