There are a lot of cool command line options available to VSQL. One of my favorites is the –b option which causes Vertica to “beep” when a command completes. This is very useful if you are running a very long sequence of SQL commands via a script. You can go off and do other things while the script runs. VSQL will “beep” once letting you know later that the script has completed!
Example:
[dbadmin@SE-Sandbox-26-node1 ~]$ cat beep.sql
SELECT version();
SELECT sysdate;
SELECT user;
SELECT 'SOME_DATA';
SELECT 'SOME MORE DATA';
-- Alot more stuff...
SELECT sysdate;
[dbadmin@SE-Sandbox-26-node1 ~]$ vsql -bf beep.sql -o beep.log
<< I heard a “Beep” >>
[dbadmin@SE-Sandbox-26-node1 ~]$ cat beep.log

Vertica Field Chief Technologist
I've had the privilege of working with many database technologies in my career. But after being introduced to Vertica in May of 2011 as a client, I was hooked on the new technology after witnessing a query run in milliseconds that had previously ran for hours on the legacy database we had in place. It was then that I knew I wanted to eventually join the Vertica team, and 4 years later I did! I am currently a Vertica evangelist and am ready to help you get on board! Please feel free to reach out to me with any questions you have about Vertica and make sure to follow my Vertica Quick Tips!
