How to list just directories ( the correct way)
September 21st, 2007 mysurface Posted in Common, ls | Hits: 16357 |
I have wrote a post stated that there are no direct ways to list just directories, and wrote a bash scripts using find to list the directories. I had made a WRONG statement. We can list just directories with ls -d, thanks to Ntropia who leaves me a comment.
Before that I had tried hard to use ls -d to list just directories but failed, therefore I wrote a bash script uses find to do that. It seems Ntropia provided a better solution and it is straight to the point, so let just treat the previous post as examples of find command.
The simplest way of list just directories
ls -d */
You can list the directories start with letter b
ls -d b*/ Further more list the subdirectories of the directories start with letter b
ls -d b*/*/ The outcome will be look like this

backup/ccbe/ backup/wplbe/ bt/çŽ‹åŠ›å® - 改å˜è‡ªå·±/
backup/full/ bin/ffmpeg-0.4.9-p20051216/
Bare in mind the command lines above do not list out the hidden directories, to list hidden directories
ls -d .*/Yes, you can also list with details, and with nice colors.
ls -d .*/ -lManual of ls should at lease gives a line of example on how to list just directories, ls capable of doing that but it seems to like easter egg for me.
Updates
In fact, I had done the post of list just directories long time ago, :P

ls is a very powerful command, but in its simplest forms it really seems counterintuitive. For example:
ls
As you would expect it, lists the current directory contents.
ls *
Lists the contents of all the subdirectories of the current directory (?)
ls -a
The same as ls, but including hidden contents.
ls -d
ls -ad
Just a dot! Hardly useful.
ls -d *
ls -ad *
The man page says “-d list directory entries instead of contents [...]“. But this just gives the same as ls. The -a switch *does not* include hidden contents.
ls -d */
ls -ad */
Just the directories, but not the hidden ones. The man and info pages don’t mention the slash trick, so I don’t know how is one supposed to learn it.
I could go on and on. One of the reasons I use mc for file management is the complexity of ls and find. Maybe the dir command should have been for a simpler, user-friendly version of ls instead of an alias.

Is there a way to list just the files?
