how to search for a string within last 15 records
Hi,

I have a oracle log file through which I search for a string "ORA-' and if it is present, the job will fail. IF grep('ORA-' $LOGFILE) is used to determine whether the job should fail or not. Log file is populated with help of a sql script

Once the job failed few weeks back to connectivity error. Since grep scans the whole log file, every week the job is failing eventhough script has ran fine.

Is there a way to run grep or find command within last 15 lines of the log file ?

Regards,

Krishna

You could use tail to pipe the last 15 lines of the file into grep.
