In zsh, you could do something like this:


##start

IFS=$'\0'
FILES=($(find some/directory/ -print0))
unset IFS

if [ ${#FILES[@]} -eq 0 ]; then
  #do something
elif [ ${#FILES[@]} -eq 1 ]; then
  somecommand ${FILES[0]}
else
  i=0
  while [ $i -le ${#FILES[@]} ] 
  do
    othercommand ${FILES[$i]}
  done
fi

##end

(not tested)

I don't think you can specify a null character in IFS for bash, though I
could be wrong.
