Hello ,
i am on linux,
and im trying to figure out why my cp command cant copy one file.
I am trying to use variable in which i stored path to location where is file i wish to copy.

[oracle@g5 ~]$ echo $ORA_ALERT_LOG
/u01/app/oracle/diag/rdbms/ring11/ring11/trace
[oracle@g5 ~]$
[oracle@g5 ~]$
[oracle@g5 ~]$ pwd
/home/oracle
[oracle@g5 ~]$ cp -p $ORA_ALERT_LOG/alert_ring11.log $ORA_ALERT_LOG/alert.ring11.log$DATE
[oracle@g5 ~]$
[oracle@g5 ~]$ echo $DATE
05_12_09
[oracle@g5 ~]$ ls -l /u01/app/oracle/diag/rdbms/ring11/ring11/trace/alert_ring11*
-rw-r----- 1 oracle oinstall 25859055 2009-05-12 10:52 /u01/app/oracle/diag/rdbms/ring11/ring11/trace/alert_ring11.log

I dont know why cp command don't use path got from $ORA_ALERT_LOG variable...
Should i use it in some other way ?

Your copied file name is alert.ring11* not alert_ring11* .
