# Usage: ./find-all.sh search-string
# search-string does not need " or *

if [ -z "$1" ] 
then
    echo "Usage: ./find-all.sh search-string  (note: no need for \" or *)"
    exit 0
fi

printf "\nSearching everywhere for \"*$1*\" (case-insensitive) ...\n\n"

find / -iname "*$1*" -not -path "/System/Volumes/Data/*" -print 2>/dev/null

Option: copy this script into /usr/local/bin. You may rename it mv find-all.sh find-all.

In that case, from anywhere in the system, you can type:

$ find-all something

Searching everywhere for "*something*" (case-insensitive) ...

$
