LinuxQuestions.org - ls to view directories only

That's right, the directory list isn't being generated by ls, but by shell globbing. ls is only reading the list to give you detailed info.

For a simple list, you can even do this:

Code:

echo */

Different commands process their option arguments in different ways. Common variants are:

Flag options must appear at the beginning of the argument list. Once the first non-flag argument or explicit "--" argument is encountered, everything that follows will be treated as an ordinary (non-flag) argument even if it happens to begin with a '-' character. This is the old-style Unix method of option processing.
Flag options can occur anywhere in the argument list until a "--" argument explicitly terminates option processing, and all options apply globally. This implies that the entire argument list is scanned for flag arguments before any non-flag arguments are processed.
Flag arguments can be interspersed with non-flag arguments (again, subject to "--" terminating option processing), and each option applies only to the arguments that follow it in the list. (Example: the tar "--directory=xxx" option)

It appears that the ls command is in the second category.

It seems everyone is doing it the hard way. The simplest way to list a directory and only the folders, without the full path is:

ls -F <whatever path you want> | grep /

For example

ls -F ./ | grep /

will list the local directories

ls -F Documents/ | grep /

will list all of the directories in the folder Documents

Hope this helps!

the simplest way is:

Code:

ls -d */

To also show hidden directories, I prefer:

Code:

ls -al | grep ^d

If you're not stuck on using ls, the command find . -maxdepth 3 -type d would list all directories under ./, for no more than three levels. Here's an example:

Code:

$ cd Scripts/

$ find ./ -maxdepth 2 -type d

./

./dash

./InitRD

./gawk

./gawk/igawk_backup

./gawk/Gutenburg

./tmp

./bash

./bash/Xfce

./bash/Mounting

./bash/Housekeeping

./bash/Network

./bash/bashsimplecurses-0.0.1-alpha

./bash/Testing

./SQLite

./Floppy

./Older Scripts

./Init

...

<edit>
Or you could use this:

Code:

$ tree -dL 2

Sorry, but not only is this command unnecessarily complicated, it also doesn't work. It will break on any directory containing whitespace, thanks to the shell performing word-splitting after the command is expanded.

($(..) is highly recommended over `..`, BTW.)

Code:

$ mkdir 'aa bb'



$ ls -dl $( find . -type d )

ls: cannot access ./aa: No such file or directory

ls: cannot access bb: No such file or directory

If you want to run ls on the output of find, use its -exec option instead.

Code:

$ find . -type d -exec ls -dl '{}' \+

drwxr-xr-x 3 david david 72 Apr 22 00:33 .

drwxrwxr-x 2 david david 48 Apr 22 00:33 ./aa bb

Or if you're using gnu find, which you should be on Linux, you can use it's own built-in -ls option to get pretty much the same output.

Code:

$ find . -type d -ls

 80205    0 drwxr-xr-x  3 david    david          72 Apr 22 00:33 .

313973    0 drwxrwxr-x  2 david    david          48 Apr 22 00:33 ./aa\ bb

alias lsd="ls -d \.#*(/)"

with setopt extendedglob

Just the DIRs please.
