This is a little more complicated, but perhaps the cron job could be a simple script that would compare the file size to what it was during the last cron job. So, if the file size is the same as it was 10 minutes ago, chances are it's finished uploading.
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mark Freeze Sent: Thursday, April 07, 2005 8:33 AM To: Triangle Linux Users Group discussion list Subject: [TriLUG] Scheduling file transfers A year or so ago I had a problem downloading a file via ftp onto a Windows box with WS_FTP. The file was about 100MB and I started downloading the file while my customer was still uploading, so I only got about half of the file. WS_FTP allowed me to do this with no error. (Which I thought was kinda crazy.) Now I have an offsite ftp spot that my customers use to send me files at random times during the day. I want to automatically download and process these files onto my box as soon as they appear on the site so I was thinking that I would scehedule up a cron job to look for these files every 10 min. When I do this am I going to have the problem of seeing the file and trying to get it as they are uploading? Some of these files are over 100MB and might take my customer a while to upload. Someone told me to make sure that I have exclusive access to the file before I download it, but since I have no control over the ftp server I'm not sure on how to accomplish that task. Any help will be greatly appreciated.
