How to `ls` only one level deep?

Question

I have lots subdirectories containing data, and I want a short list of which jobs (subdirectories) I have. I'm not happy with the following command.

$ ls H2* H2a: energy.dat overlap.dat  norm.dat zdip.dat ... (much more) H2b: energy.dat overlap.dat norm.dat zdip.dat ...  (much more) 

This needless clutter defeats the purpose of the wildcard (limiting the output). How can I limit the output to one level deep? I'd like to see the following output

H2a/ H2b/ H2z/ 

Thanks for your help, Nick

Answer 1

Try this

ls -d H2*/ 

The -d option is supposed to list "directories only", but by itself just lists

. 

which I personally find kind of strange. The wildcard is needed to get an actual list of directories.

UPDATE: As @Philipp points out, you can do this even more concisely and without leaving bash by saying

echo H2*/ 

The difference is that ls will print the items on separate lines, which is often useful for piping to other functions.
