./oradiag_oracle
./oradiag_oracle/diag
./oradiag_oracle/diag/clients
./oradiag_oracle/diag/clients/user_oracle
./oradiag_oracle/diag/clients/user_oracle/host_17562726_80

You got a request to find the top 10 files which occupy more space in home directory

[oracle@exdbadm01 ~]$ find /home/oracle/ -type f -print -mtime +7 -exec du -csh {} \; | sort -nr|head
