I'm not quite sure just what it is that you're wanting to do, but if my
guess is correct, this should get the job done:

if [ -e "/path/to/*.log" ] ; then
  for i in /path/to/*.log ; do
    /bin/rm "$i" &>/dev/null && echo "Removed $i." ;
  done
fi

That should run the removal loop only if there is at least one log file
present to be removed, and report removal only if the removal actually
succeeded - rather than claiming success even if, e.g., the file could
not be removed because appropriate write permission was missing.

If that isn't what you want to do, then you'll need to explain better
what it is you're trying to accomplish.
