I have seen this done with a couple of GNU tools in the past. The
problems that usually stopped this was that too many strange consoles
seem to be a pipe at somepoint and so it spits out the wrong format at
the wrong time. It is usually easier to just add a flag like : --long
to get the detailed stuff and have a default of it being scriptable
output.
