choosing a random folder in a folder
I need my script to choose a random folder within a folder and set that folders name as a variable.

I can list all folders within a folder using

Code:
#!/bin/bash

dir='/folder'
file=`/bin/ls -1 -l "$dir" | egrep '^d' | sort --random-sort | head -1`
path=`readlink --canonicalize "$dir/$file"` # Converts to full path

echo "The randomly-selected file is: $path"
echo "$file"
echo "$path"

Say my folder structure is

folder
|____folder01
|____folder02
|____folder03

By using the code above I can list the folders as so.

The randomly-selected file is: /folder/drwxr-xr-x 2 user user 4096 2012-04-14 14:53 folder01
drwxr-xr-x 2 user user 4096 2012-04-14 14:53 folder01
/folder/drwxr-xr-x 2 user user 4096 2012-04-14 14:53 folder01

I just want it to display 'folder01' and not 'drwxr-xr-x 2 user user 4096 2012-04-14 14:53 folder01'

Any help would be greatly appreciated.

Cheers
DV

I think the issue is with this command

ls -1 /folder/

I just need this command to just list directories and not files.
