Question

 ls | grep -v "//|=/|@/||"

will ls then piped to a reverse grep work?
This question seems to not meet the quality standards, maybe if i write more random things
it will be a quality question.

If you do this you should explicitly add the -F flag.

ls -F | grep '...'

Using find would be more elegant, in my opinion:

find . -type f                # Recurse into subdirectories.
find . -maxdepth 1 -type f    # Do not recurse.
