I fail to see what crontab has to do with whether the operation is push or pull. The app is free to choose what method is appropriate and has no bearing on whether it was started from crontab or the command line or wherever. > If you use crontab, you could be in danger of having multiple processes > starting up to ftp the same files.

This is true regardless of starting method (crontab, etc). A semaphore of some sort is appropriate. -- ,-/- __ _ _ $Bill Luebkert Mailto:[EMAIL PROTECTED] (_/ / ) // // DBE Collectibles Mailto:[EMAIL PROTECTED] / ) /--< o // // Castle of Medieval Myth & Magic http://www.todbe.com/ -/-' /___/_<_</_</_ http://dbecoll.tripod.com/ (Free site for Perl/Lakers) _______________________________________________ Perl-Unix-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
