SHELL script Monitoring oracle alert Log

Monitor alert Lo

Idea: compare the current last line with the last scanned line according to the alert log line number, which is greater than or equal to the last scanned line from the last scanned line to the last line.

The script automatically scans the specified keyword, which in this case is ORA-, and then simply deploys it to crontab.
