Hello ,
I have process that picks up multiple files from a directory forks
child processes and each child process works on a batch of files and
finishes the task


So what is the best way of doing it , preferably using a perl program

I am thinking of this

Parent process reads filenames from a file continuosly ( using tail )
divide tasks into $MAXCHILD processes but not exceeding $MAXBATCHSIZE
per child

I am not sure what is the best way.
Can someone pls give me some ideas
