Thanks a lot methyl, that is so very embarrassing SmilieSmilie ....

All good now ... still stumped on why the -d returns true for a symbolic link though, it's like it is trying to check whether the link that the symlink is set to is a directory.

I can live with doing the -h then the -d for the time being ... thanks again for pointing out my mistakes ... need to grab some more coffee I guess

Below is an example where I create another symbolic link but the actual directory /tmp/x does not exist and my original script works like how I want it to. Any chance that there is a test where it will not try and resolve what the symbolic link is linking to?

Code:
tmp $: ./x.ksh
Checking dir1
... dir1 is a directory
Checking dir2
... dir2 is a directory
Checking dir3
... dir3 is a directory
Checking dir4
... dir4 is a symbolic link
tmp $: cat x.ksh
#!/bin/ksh

for checkdir in dir*
do
   echo "Checking ${checkdir}"

   if [[ -d "${checkdir}" ]] ; then
      echo "... ${checkdir} is a directory"
   elif [[ -h "${checkdir}" ]] ; then
      echo "... ${checkdir} is a symbolic link"
   fi
done
tmp $: ls -ltrd /tmp
drwxrwxrwt  79 root     root      221472 Sep  1 12:41 /tmp
tmp $: ls -ltrd /tmp/x
/tmp/x: No such file or directory
tmp $:

DH_MOVEFILES(1) 						     Debhelper							   DH_MOVEFILES(1)

NAME
dh_movefiles - move files out of debian/tmp into subpackages SYNOPSIS
dh_movefiles [debhelperoptions] [--sourcedir=dir] [-Xitem] [file...] DESCRIPTION
dh_movefiles is a debhelper program that is responsible for moving files out of debian/tmp or some other directory and into other package build directories. This may be useful if your package has a Makefile that installs everything into debian/tmp, and you need to break that up into subpackages. Note: dh_install is a much better program, and you are recommended to use it instead of dh_movefiles. FILES
debian/package.files Lists the files to be moved into a package, separated by whitespace. The filenames listed should be relative to debian/tmp/. You can also list directory names, and the whole directory will be moved. OPTIONS
--sourcedir=dir Instead of moving files out of debian/tmp (the default), this option makes it move files out of some other directory. Since the entire contents of the sourcedir is moved, specifying something like --sourcedir=/ is very unsafe, so to prevent mistakes, the sourcedir must be a relative filename; it cannot begin with a `/'. -Xitem, --exclude=item Exclude files that contain item anywhere in their filename from being installed. file ... Lists files to move. The filenames listed should be relative to debian/tmp/. You can also list directory names, and the whole directory will be moved. It is an error to list files here unless you use -p, -i, or -a to tell dh_movefiles which subpackage to put them in. NOTES
Note that files are always moved out of debian/tmp by default (even if you have instructed debhelper to use a compatibility level higher than one, which does not otherwise use debian/tmp for anything at all). The idea behind this is that the package that is being built can be told to install into debian/tmp, and then files can be moved by dh_movefiles from that directory. Any files or directories that remain are ignored, and get deleted by dh_clean later. SEE ALSO
debhelper(7) This program is a part of debhelper. AUTHOR
