combine find, xargs and grep in one command

g0.sh

#!/bin/bash
GREPARGS=()
FINDPATHS=()
while [[ $# != 0 ]]; do
    if [[ -d "$1" ]]; then
        FINDPATHS+=("$1")
    else
        GREPARGS+=("$1")
    fi
    shift
done
find "${FINDPATHS[@]}" -type f | x0 grep "${GREPARGS[@]}"

So, now i discovered that grep has a -r option, to recursively search a directory.
