Listing directories first with 'ls' command

Lufbery · 01-15-2007, 04:24 PM

Hi all,

I've been working with Linux now for half a year or so. I generally find its command line interface superior to DOS except for one command, the 'ls' command.

I'd like the equivalent of the dir command: 'dir /o:g' which lists directories first.

I've looked at the info and man pages, and I'm not sure how to get 'ls' to do that. If anyone knows please tell me.

Thanks in advance,

If you like that command line you can make an alias so you don't have to remember it. Edit your home directory file .bashrc and add a line like this.
alias dir="ls -l | sort -k 1.1,1.2 -k 8.1 -f | less"

Great stuff! Thank you.

Okay, that worked, except that the directories are listed after the other files. I guess I'll have to dig into the sort command a bit more.

EDIT: fixed it. I added the -r option to the sort command.

The alias looks like this now:

alias dir='ls -l | sort -k 1.1,1.2 -k 8.1 -r'

I found that there's generally no need to pipe to the less command by default; I can allways type 'dir | less' and get the same result.

I hope theres no prob if i post a query of mine.
How can I use the command line to list all files of a particular extension recursively?
What I am trying to do is go to a particular directory and then search all the directories inside this directory for certain filetypes.

I tried ls -R *.mp3 or ls -R *.mp3 ./ but it doesnt work.
If I do ls|grep -R --include==*.mp3 ./ it returns a whole lot of garbage...I know grep searches even for the contents of the file, but just gave it a try.

Im still new to the command line.

Code:

find . -name "*.mp3"
