Shell script monitors Oracle alert logs

Monitoring Alert logs

Idea: Follow the alert journal line number to the current last row and the previous scan row compared to the last scanned row from the previous scan line to scan to the final line

The script automatically scans for the specified keyword, where it is specified as ora-, and then only needs to be deployed to crontab.
