If you are on a linux system and all you care is to do a one way sync from folderA to folderB, why don't you check out existing utilities like rsync or unison? I've used both and they are quite stable utilities. If you are on Unix, then you can try to look for rsync ported for your platform.

i am on iphone... i am quite confused with all the environments, i try to read of the internet but things dont make sense sometime Smilie
I dont think rsync will work for me....

As of now, i am trying Tony's solution, hope it works Smilie but thank you for the suggestion.

so i retried: here is my script

Code:
#!/bin/bash


PREVLATEST=""
while [ 1 ]; do
LATEST=`ls -tr /var/mobile/Media/DCIM/100APPLE | tail -1`
if [ "${LATEST}" != "${PREVLATEST}" ]; then
  cp `ls -tr "/var/mobile/Media/DCIM/100APPLE/${LATEST}" | tail -1` "/var/mobile/Media/DCIM_2/${LATEST}"
  PREVLATEST="${LATEST}"
done

i get:


localhost:/private/var/stash/libexec.C9Fmd1/cydia root# sh TAT.sh
-sh: localhost:/private/var/stash/libexec.C9Fmd1/cydia: No such file or directory
localhost:/private/var/stash/libexec.C9Fmd1/cydia root# TAT.sh: line 10: syntax error near unexpected token `done'
> TAT.sh: line 10: `done'

any suggestions?

Your if block is not closed by a "fi".

Mea culpa!

Put a fi in a line before the done, sorry!

Also the line:
Code:
cp `ls -tr "/var/mobile/Media/DCIM/100APPLE/${LATEST}" | tail -1` "/var/mobile/Media/DCIM_2/${LATEST}"

may be simplified to:
Code:
cp "/var/mobile/Media/DCIM/100APPLE/${LATEST}" "/var/mobile/Media/DCIM_2/${LATEST}"

Also why are you trying to use an NFS address in a script?:

localhost:/private/var/stash/libexec.C9Fmd1/cydia

Drop the "localhost:"

Carrying on rikxik's suggestion if you simply want to copy only new or changed files from foldera to folderb then the following will do that:
Code:
find foldera | cpio -pdmv folderb

The cpio(1) command will not copy files into folderb that already exist AND are the same as the in foldera, if any files are new or changed in foldera then cpio will copy them.

So for the folders you mentioned before:
Code:
SOURCEFOLDER=/var/mobile/Media/DCIM/100APPLE
TARGETFOLDER=/var/mobile/Media/DCIM_2
while [ 1 ]; do
  find ${SOURCEFOLDER} | cpio -pdmv ${TARGETFOLDER}
  sleep 3
done

Drop the v parameter crom cpio once you are happy it is doing what you want it to.
