I wanted an alias or program, lsd, that would show just the directories in a directory. My first take was this alias.

alias lsd='ls -d `find . -maxdepth 1 -type d -print | grep -v "^.$" | cut -c 3- `'

It worked fine until I got to directory names with spaces, so I moved it into a script so I could look at it, and as a first take, thought I'd use sed to replace any spaces with "\ " like you would from a command line and that was a disaster. I finally got it to work, and I'll include the short script below, but does someone know of a better, shorter way of doing it? (The
section on args is there so later I can override the depth if I want to.

One strange thing is that the grep is to get rid of the ./ dir which is always there, and I don't really need to see it. Great! But if there's no directories in a directory, it lists the ./ anyway! I kind of like it, but I'd like to understand how or why!

#! /bin/bash
export IFS="
"
mygetdir='.'
for arg in $* ; do
case $arg in
*) mygetdir=$arg ;;
esac
done
cd >& /dev/null $mygetdir
echo ~~~ $mygetdir ~~~
ls -F -d `find -L . -maxdepth 1 -type d -print | sed 's/.\///' | grep -v "^.$"`
