If I do an "echo list media | bconsole", I see the following:

You have messages.

Everything but the part in the table is not useful to my query.  The
table, in turn, is formatted for human readability, with various ASCII
line drawing characters.  A batch mode, such as supplied with some
other tools, would not include anything but the table without line
drawing characters.

I've worked around this in the past, BTW, by doing:

  echo list media pool=Daily|bconsole |grep '^|'|tail -n +2|sed 's,|,,g'

It would be nice to be able to do this kind of thing without playing
shell script games, though.  Thanks!
