Hi,
If you check the man page for find you will find a very nice little switch called -exec
check it out! It sould fix your problems!
example :
find ./ -mtime +7 -exec mv {} oldfiles/ \;
Will move all files with mtime +7 to oldfiles/
(the {} will be replaced by the filename) The -exec command will be runned for every file it finds..
Test it in a test environment before applying it to production data just to be on the safe side
Better safe then sorry
