    That would be interesting, and it would be useful, but IMHO it would
    be better to write a bash script to do it. Make a ~/bin directory, edit
    ddir:
     
    #!/bin/bash
    ls -al | grep ^d

    save it in *your* bin directory, not /bin, but /home/you/bin, or
    ~/bin for short. Then make it executable:

    $ chmod +x ddir

    Put your ~/bin directory in your path in ~/.bashrc

    #path - this line is a comment

        export PATH=$PATH:/home/dra/bin

    Look at all the aliases in there! Point is that a bash script
    is slower, but you can do more with it, and the difference
    in speed won't be important unless you are using a machine
    that is really really really old. Aliases are like DOS macros,
    in memory, and bash scripts are like DOS batchfiles, on disk.

    tree is prettier than ls for this. daveA
