-Re: How to read multiples files getting continuously updated

Thanks for quick reply, as you pointed out Exec Source does not provide
reliability, which is required in my case, and hence it is not suitable.
So which other inbuilt source could be used to read from many files ? Just
one other requirement is file name s are also dynamically generated using
time stamp after every 5 mins.
