Thank you everyone for the quick comments,... I'm not looking to for a very precise measure of the computation time .. Jus a type of guess that can give the user a fair idea abt it .. As for the code, its really long, so i'll jus explain the process flow
in reply to Estimating computation time perl scripts
The program has a lot of subroutines and performs comprehensive checks on multiple files simultaneously ( about 6 files in all .. total size : approx 9 MB .... )
I knw how to program the progress bar., its jus the count (total time )thats a bit of a worry ... Help appreciated..!!
