Uri post the output line from that command. do not let your emailer mung it

easier ways to get it with a regex and not with split.
I think you may be right. I would like to pull the numerics out from the id=

that will match 'grid=123' or 'foo=34 noid=123' etc. the .* is allowing
anything before the id. it may work here as no field other than id ends
in 'id' but it is a poor regex. don't use *. unless you mean
