yes this is right i need the most recent one... as after the log is written it takes a
few or more seconds for the command to return.
the "discover" or delta can be from a few seconds to a few minits (depending on the
number of elements configured on the device)

this looks good to me i shall try it out tomorro, but i had a look on CPAN and found a
golb module that may help???

there are a "lot" of file in the dir, they are cycled / cleaned up, by a scheduled job
every week,
but some will be a month old (ones the result from a monthly scheduled job)

humm if i have this list, can i "grep" through and find the one that contains "key"
(ie host name)
that would do the trick...

this could get messy as i could be running say 20 discovers and only after each one
will the log file be ceated.
+new log could be created by non discover activities.
thanks for your help
