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.

fnext

NEW(1)								     [nmh-1.5]								    NEW(1)

NAME

       new - report on folders with new messages

       fnext - set current folder to next folder with new messages

       fprev - set current folder to previous folder with new messages

       unseen - scan new messages in all folders with new messages

SYNOPSIS

       new [sequences] [-mode mode] [-folders foldersfile] [-version] [-help]

       fnext is equivalent to new -mode fnext

       fprev is equivalent to new -mode fprev

       unseen is equivalent to new -mode unseen

DESCRIPTION

       New  in	its  default  mode  produces  a  one-line-per-folder  listing of all folders containing messages in the listed sequences or in the
       sequences listed in the profile entry "Unseen-Sequence".  Each line contains the folder, the number of messages in the  desired	sequences,
       and the message lists from the .mh_sequences file.  For example:

	    foo     11.* 40-50
	    bar    380.  760-772 824-828
	     total    391.

       The `*' on foo indicates that it is the current folder.	The last line shows the total number of messages in the desired sequences.

       New crawls the folder hierarchy recursively to find all folders, and prints them in lexicographic order.  Override this behavior by provid-
       ing foldersfile containing the pre-sorted list of folders new should check, one per line.

       In fnext and fprev modes, new instead changes to the next or previous matching folder, respectively.

       In unseen mode, new executes scan sequences for each matching folder.

FILES

       $HOME/.mh_profile	  The user profile

PROFILE COMPONENTS

       Path:		    To determine the user's nmh directory
       Current-Folder:	    To find the default current folder
       Unseen-Sequence:     The name of the unseen message sequence

SEE ALSO

       scan(1), mh-format(5)
