Hi,

I'm looking for a way to read log files in real time, so that each time a
new entry appears in the file I can perform a search/query (whatever
really!) on it.

it's odd really, as I expected this to be a very common scenario and yet I
can find nothing on it!

I think there maybe some way to achieve this using the seek and tell
commands but I can't quite fathom it out.

any suggestions?

thanks,
Ad
