[ale] Bash Script

[dsj at dsj.net (David S. Jackson)]

Hi,

Is there a way to show ONLY directories from ls?  I couldn't think of a way,
so I wrote a little thing called "lsd".  

<quote>

#!/bin/sh

#  This script lists only directories in the current directory--I
#  don't know how to make ls do that!  So I wrote this little script.

curdir=${1:-$PWD}

echo $curdir                      #  This is for debugging

for dirname in $(ls $curdir)
  do
     if [ -d $dirname ]; then echo -ne "\t $dirname"

     fi
  done

echo -e "\n"

</quote>


First, for some reason, I can't seem to get the script to act on the $1 argument.
When I enter 

lsd /home

I should get all the directories in /home.  But that doesn't happen.  What
am I doing wrong?

Second, is there a way I can "echo" a line across the screen similar to ls
-C?  It works the way I have it (with echo -ne) but the column doesn't wrap
evenly onto the next line; it breaks in the middle of a word.  Any hints?

Thanks much!

Dave
