Hello Stefan,

In a script, you can do:


echo -e "sql\nSELECT......ORDER BY volumename INC;\n\nquit\n" | bconsole


The echo -e: enable interpretation of backslash escapes

The `\n` in the script are line feeds.  The two `\n\n` in a row get you out of the bconsole SQL interface.


This method (echo -e) allows you to enter multiple bconsole commands in one session using echo.

And, to make things more clear with the long SQL query, you can split the query up, by appending backslashes to the end of 
each line like:
----8<----
echo -e "sql\nSELECT
 Media.MediaId, Media.VolumeName, Media.PoolId, Pool.Name AS Pool, \
          Media.Slot, Media.Slot <> 0 AS InChanger, Media.FirstWritten, Media.LastWritten, \
          Media.VolStatus, GREATEST(0, (extract('epoch' from LastWritten + Media.VolRetention \
          * interval '1second' - NOW())::bigint)) as ExpiresIn, Media.VolBytes FROM Media \
          INNER JOIN Pool ON Media.PoolId = Pool.Poo;\n\nquit\n" | bconsole
----8<----


Hope this helps.
Bill
