Is there a way to clone host definitions in bb-hosts?

Our cluster nodes are node000 -> node999

We do the following:

for I in `seq -w 0 999`; do echo "`getent hosts node$I | cut -d' ' -f1`
node$I # ssh etc"; done > /tmp/output.txt

What I do in cases of this are to use for, if/then kind of things.

Example, I have a log that sticks in lines like

1.2.3.4 n y
2.2.5.6 x z

And I find repeating lines by IP in $1 then get a count of them using wc.

I can show you the script if this didn't come out clear.

What I'm looking for is a more helpful answer; loading several files
up into vi and doing a search and replace on all lines that match a
pattern feels kludgy to me.

Get familiar with bash or tcsh =)

I'm using hobbit for monitoring a compute cluster of nearly 1000

length down, but my included files are comprised of hundreds of hosts
all identical except for the ipaddresses and hostnames.

Surely there must be a way to template this, I just can't find it in
the bb-hosts manpage...

==============================

I'd like to be able to define the tags in a template, and simply use
that template.  Does this mechanism exist in bb-host?  That way
if/when I need to change the tags for all my hosts, I only need to do
it in one place, and not on every line in 3 different files.
