Fork me

rhowerton has asked for the wisdom of the Perl Monks concerning the following question:

I would like to know where there is a tutorial on fork(); I have a little pet project where I want to use Net::FTP and fork several processes to act as clients, but I have no idea how to control how many forks happen at one time. For instance, I would like to ftp 50 files but only ftp 5 at a time. When any 1 ftp ends I would like a new one to take its place. Anyway, I would just like someone to point me in the right direction. Thanks.

Check out this node. With some help from past posts, I posted some easy to follow sample code using ForkManager. It rocks, and I'll never program straight forks again now that I know how to use it! And don't forget to check SuperSearch before you post a question. I've seen maybe 4 forking questions in the last week. :)	[reply]

Hmm... I keep saying this on PM, check out Network Programming with Perl It's a really good book and does exactly what you are asking and more I really should get royalties for pimping this thing so much :) "Nothing is sure but death and taxes" I say combine the two and its death to all taxes!

Good tidbits in perldoc perlipc. Also, geared for C, but a great explanation is in Advanced Progamming in the Unix Environment, Chapter 8 (W. Richard Stevens). Lastly, it's already mentioned in other nodes, but based on your description of what you want to do, Parallel::ForkManager might be a great help.	[reply]

Check out Proc::Queue. Very cool module that does exactly what you seek.	[reply]
