sorry couldnt figure out how to give the spaces at the beginning of the line...and not a lot of time too...my apologies to fellow monks...this can be extended to any numbers...i have given example of 1.pl...you can do this till n i guess and also you can change the number of forks per file....hope this aint bad perl hacking...:-s ...cheers
