echo with each parameter on its own line

Question

I would like an output similar to ls -1d, but I don't want to check if each file exists. I would prefer to just list the files. I could use echo, but echo only puts a space between files.

How can I put a return between the files/parameters?

Answer 1

for loop.

for f in *
do
  echo "$f"
done

Answer 2

As far as I understand from your question, you can use find

find /opt -maxdepth 1

For printing file names only

find /opt -maxdepth 1 -type f

For printing directory names only

find /opt -maxdepth 1 -type d
