   You can for example check only sizes and time of the last modification for each file, this would be much quicker and probably fit your needs:

   du -a –time $FOLDER1 > /tmp/folder1
   du -a –time $FOLDER2 > /tmp/folder2
   diff /tmp/folder1 /tmp/folder2

   Maybe you can use rsync?

   You can use rsynch to make the 2 directories the same if that is your goal..

   rsync -av –delete /home/backup/ch3snas/ /home/backup/server/data

   the –delete make sure the files that are deleted in the source are also deleted in the target so the target will not grow out of diskspace.

   rsync has a lot more options ofcourse..

   rsync itself for the purpose is too slow
   my ’script’ already works, but need to compare the target folder with the source if they are equal, if they are equal than the source files can be removed if not (due to failure in ftp) than the script must stop

   FOLDER1=$’/home/backup/server/data’
   FOLDER2=$’/home/backup/ch3snas/`date “+%d-%m-%y”`’
   du -a .time $FOLDER1 > /tmp/folder1
   du -a .time $FOLDER2 > /tmp/folder2
   Compare=$(diff /tmp/folder1 /tmp/folder2)

   FOLDER2 does not work as I want it. Folder2 has the date of today, and this folder must be compared, but the date command seems not to work as environment

   Dennis,

   Kan het mis hebben, maar mis je niet 1x else ????

   In het begin 2x if then, naar na wat commando’s maar 1x else….

   Je mist de else van if [ ! -n "$Compare" ]; then
   of van if [ -e data ] then

   volgens mij…

   Hi Robbie, thanks for your answer

   I have solved my issue by buying a script for bluequartz..
   that was more easy than all the hassle I had to do myself programming
