I am trying your code:

until [ "$(echo "$DIR/"*)" = "$DIR/*" ]
do
sleep 2
done

But it says Illegal variable Name

I am using tcsh.

It is POSIX compliant shell code. It will not work with tcsh. You can put this at the first line of your script:
Code:
#!/bin/bash

or this: #!/bin/sh or #!/bin/ksh (or #!/usr/xpg4/bin/sh if you are on Solaris).

So I need the tcsh compliant code only.

Code:
#!/bin/tcsh
 while (1)
      if (`find yourpath/|wc -l` > 1) then
         echo "Not Processing -> [ waiting for empty ]\n File list ..\n"
         ls -l yourpath/|grep -v total
         echo "" ; sleep 2
      else
         echo "Processing now ..\nProcess is now complete";
