Maybe wait and repeat?
Code:
until find /path/FTP. -type f -size 0 | awk '{print; exit 1}'
do
  sleep 28800
done

Instead of until or while you can also use an if clause. It gets the exit status of the awk command, 0 normally, 1 if a zero-file was found.
NB in the shell an exit status 0 is a true condition (for practical reasons).
You can suppress awk's output with >/dev/null, this doesn't affect its exit status.

Just seeing the proposal with line.
Code:
while find /path/FTP. -type f -size 0 | line
do
 sleep 28800
done

Default is to search in $PATH. EXAMPLE
# shell script awk=`shtool path -p "${PATH}:." gawk nawk awk` perl=`shtool path -m perl` cpp=`shtool path -m cpp` revpath=`shtool path -r path/to/subdir` HISTORY
The GNU shtool path command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1998 for Apache. It was later taken over into GNU shtool. SEE ALSO
