Subject: dbl output and record name aliases

Hi,

Many installations use the output of a 'dbl' command on an IOC to create a "list of records on this IOC" file that gets scanned by some other service. (E.g. IRMIS, ChannelFinder, PV search databases, etc.)

The 'dbl' command lists alias names as if they were records, with no distinction. In many cases this is desired (e.g. for a PV search database), in other cases listing only names of "real" records would be preferred (e.g. for consistency checks, some ChannelFinder applications).

Running 'dbl "" NAME' does create something that shows that extra information (both sides are equal for a record, else the left side is an alias for the right side) but obviously changes the output format.

What would be the smartest way to allow both options and make everyone happy? Should we go for an entirely new command with a new output format that maybe also shows the record type? ('dbl' with empty arg1 loops over the types, but does not show them.)
One-line-per-record-straight-ascii or XMLish?

Indecisively,
~Ralph
