Shellscript & Oracle: Run Script for a List of Databases

Hey all!
Quick tip/script for today: How to run same script for a list of databases quickly?

In my case I have same password/user in all databases, but in case you haven’t you can make a similar awk command to retrieve users and passwords from a file.

The list:

$: cat /tmp/dbs.cfg
db01
db02
db03
testdb

The script:

for DBSID in ${*-$(awk -F: '!/^#/ {print $1}' /tmp/dbs.cfg}
do
    print "
        connect user/password@${DBSID}
        @script_to_run.sql
        exit " |
    sqlplus /nolog >> /tmp/output_test.log
done

Hope it helps!
Cheers!
