Can rsync monitor a file system?

[Daniel Laffien]

Hi there,

I'm using the FAM tool FILESCHANGED with a small script, that calls RSYNC  
delayed after
FILESCHANGED reports a changed file in a tree, maybe this is useful for  
you.

fileschanged -r -t 10 [path] | while read file; do
         rsync [path]
done

I'm sycing the whole tree and not the single changed file, so it would be  
usefull to
filter the FILESCHANGED output during the rsync transfer, but this woul be  
heavy in
a small shell script I think...

Greetz,
Daniel
