This seems to me like one of those "more than one way" things - you could create a daemon or a cronjob to handle this for ya, depending on your needs (speed, efficiency and delay time as important factors that I can think of off the top of my head).
Anyway, whatever you end up choosing, you can use the readdir() Perl function (assuming you're running this program locally on the FTP server) to read in all the files (fyi: it also reads in '.' and '..' [but maybe just on UNIX]) and compare them using the stat() function - if any files are more recent than the last time the directory checked (which if you use a cronjob, would be the recurrence value or with a daemon, the sleep value), then those are the ones you want to download (which you could feed into a system call to ncftpput or ncftpget - the Net::FTP module may also be of use). If you're running the program remotely, I would hunch that Net::FTP can handle most of this for you (getting a list of files in the directory with file statistics and such). Hope that helps ... just some of my random thoughts on your problem. ;) Jason If memory serves me right, on Monday 11 March 2002 12:03, Craig Sharp wrote: > Ok, here is a good one. > > I need to be able to monitor a directory on an ftp server and then download > the files when they have been uploaded to the server. > > The problem is how to determine when a file is there and if a file is > there, that the file is done being uploaded from the source. > > I was going to look at a bot but I am sure that there is a way to > automatically do this with perl.
