Make `find` returns only sub-relative path in Linux？

Question

I am using find in Ubuntu to list all files in one directory into a text file. With the command below:

find ./ -name "*.txt"

I get results:

./a.txt
./dir/b.txt

But I want the results to be like:

a.txt
dir/b.txt

What should I do? Thanks!

Answer 1

Thanks to @Barmar, the below commad works:

find * -name "*.txt"

If you want sorted output:

find * -name "*.txt" | sort

If you want to save the output into txt file:

find * -name "*.txt" | sort > res.txt

Suggesting to use simple ls command. With ** glob pattern to recurse sub-directories.

shopt -s globstar
ls {,**}/*.txt
