>do not create 4hours_marker file, it seems the command have error

What had an error? The touch didn't create the file? Any error messages?

Thx Mel Burslan ,

for your latest program , does the -newer mean only compare the newer files so I need to setup a crontab job to run it in every 4 hour ? if yes , can advise if I want the program can be run at anytime to check the files in past 4 hours ( not only the newer file ) , what can i do ? thx

Yes.

Then you need to do date arithmetic to invoke touch. Or use perl. Or possibly gnu find that allows minutes in the -mtime.

can you please advise how to do it ? thx

can advise how to use find to search the files on remote server ? thx

[heaman1]

thx all,

Rather than copy the files back for comparison , is it possible to export the files to a list , then compare the lists in both servers , because copy the files back to local server , it seems increase the network traffic , can advise what can i do ? thx

It's called hand waving, you are suppose to give up. ;-) Or manually enter the touch time for 4 hours ago.
(I personally would just write a C program to subtract 4 hours.)

>date arithmetic to invoke touch.

I don't know if Clay's date script will do minutes?
Some threads that mention it and other time manipulation with perl:
