This command use '\n' as the div.
$ find . -print0
The -print0 means use '\0' as div.
Example:
lucient@lucient-X405UA:~/Downloads$ find . -print

If use -iname means ignore capital case.

The -regex is like -path, it use regular expression
lucient@lucient-X405UA:~/Downloads$ find . -regex ".*\(\.txt\|\.sh\)$"
./script1_1.sh
./out.txt

Use ! to negation find file
example find file whose name is not end with .txt
lucient@lucient-X405UA:~/Downloads$ find . ! -name "*.txt" -print
