view story

http://www.unix.com – I have directory that has some billion file inside , i tried copy some files for specific date but it's always did not respond for long time and did not give any result.. i tried everything with find command and also with xargs.. even this command Code: find . -mtime -2 -print | xargs ls -d did not give any result on console. Is there any solution to fix this. Thanks in Adv (HowTos)
