ls -d

[Guest BooYah]

[booyah@localhost booyah]$ ls -d

./

[booyah@localhost booyah]$

 

I thought the -d was supposed to list all the directories?

 

I can get what I want, a list of directories in the current directory, by piping ls to grep, but shouldn't ls -d do that in a more efficient manner?

[ezroller]

check the man page

[Guest BooYah]

Gee thanks.

 

That's where I got the -d option from in the first place. Obviously, I'm not getting something, but what?

[ezroller]

well the man entry just says this for the -d switch

 

-d

   If an argument is a directory, list only its name (not its contents); often used with -l to get the status of a directory.

 

I'll poke around

[ezroller]

these aren't exactly easy on the keyboard, but you can do:

 

ls -l|grep "^d"

 

or

 

find * -maxdepth 0 -type d -exec ls -dal {};

 

i dunno why the -d option only shows the "." kinda a PITA if you ask me.

[ezroller]

oh. here it is!!

 

ls  -d  */.

 

hmmm...that almost makes sense.

you have to send it an arguement.

hope that shows you what actually does :)

this gives the same output as

ls *

[Steve Scrimpshire]

Best I could do is this:

 

find -type d -maxdepth 1 -mindepth 1  -printf '%fn'

 

Here's an example:

# pwd 

/home/omar

# ls

You can also do this:

find /etc -type d -maxdepth 1 -mindepth 1  -printf '%fn'

 

to list all the directories under /etc. but not recursive. If you want to make it list all the directories under /etc and all the directories under those directories, take out the -maxdepth 1

Thanks guys. OK. So ls doesn't do what I want to do?

ls -d

Doesn't seem to do much of anything except verify the directory argument exists.

 

This what I do to get a listing of nonhidden directories in the current working directory

ls | grep /

 

tyme,

 

ezroller is right

ls -d ./*

lists all of the hidden directories.

 

ls *

gives me a recursive listing of everything starting from the working directory

[ezroller]

cool.

[tyme]

tyme,

 

ezroller is right

ls -d ./*

lists all of the hidden directories.

 

ls *

gives me a recursive listing of everything starting from the working directory

:shock:

 

i must have typed something wrong....

 

addition: ok, so you want a list of the directories in the current working directory? (that's what i get from your original post)

 

if so, check this sh*t out:

ls -d */

since any directory will technically have a / at the end of it's name, this does the trick 8)

[Guest BooYah]

Dagnabbit! How'd I miss that one? Especially after ezroller's tip. I thought I had tried every combination under the sun before posting here.

 

Oddly it adds an extra / to each listing , but it does do what I want.

:lol: :lol: :lol: too late tyme...ya already lost!!! have some dignity!!! :lol: :lol: :lol:

besides the "ls -d */" which is already aliased by DEFAULT by mandrake as "lsd". Yes the same group of aliases that include "ll" and "la" (my face while reading this thread --> :shock: I can't believe you didn't know how to list directories :shock: :lol: ) There are also another cool ways:

 

One as Steve Scrimpshire suggested is "find":

level 1 directories:

~$ find . -type d -maxdepth 1

all of them:

~$ find . -type d

 

Another way could be using tree:

level 1 directories:

~$ tree -a -d -L 1

All the tree:

~$ tree -a -d

 

And finally a cool emulation of tree using find+sed instead:

~$ find . -type d -print | sed -e 's;[^/]*/;|____;g;s;____|;    |;g'
