How to List files with 2 Periods (dots), or more?

Question

From terminal, how to list files with 2 dots or more then later manually judiciously rename files.

Six (6) file examples:

a..txt
b.txt.
codec-pack-2.6.1.0_en.txt
d...txt
e....
..f.txt

Using: Ubuntu 20.04.4 LTS (Focal Fossa)

Some success with

find . -type f -name '*.*.*' |sort

The above command outputs 4 of 6 files:

./a..txt
./codec-pack-2.6.1.0_en.txt
./d...txt
./..f.txt

and misses 2 files:

b.txt.
e....

The command below did not find above 2 files that end with a dot .:

find . -type f -name '*\.'

You can try something like:

ls -a *\.*\.*

the -a is to show files starting with . Here is example:

# find .
.
./..f.txt
./a..txt
./b.txt.
./codec-pack-2.6.1.0_en.txt
./d...txt
./e....
# ls -a *\.*\.*
..f.txt                    b.txt.                     d...txt
a..txt                     codec-pack-2.6.1.0_en.txt  e....

Here is example of vertical listing:

# ls -1a *\.*\.*
..f.txt
a..txt
b.txt.
codec-pack-2.6.1.0_en.txt
d...txt
e....
