Thanks for the suggestion Charles, however that still doesn't work.  CMD
now looks like this:

   CMD="/bin/bash -c 'if [ -e /var/lib/clamav/daily.cvd ]; then 
      ls -al /var/lib/clamav/daily.cvd; else echo; fi'"

and the new errors are:

   [: -c: line 1: unexpected EOF while looking for matching `''
      [: -c: line 2: syntax error: unexpected end of file

Any other suggestions?

Thanks,

-Jim P.
