UNIX for Dummies Questions & Answers

Hi ,

Please help me with a logic, how can I acheive the below.

I have a directory /eth/Src/, when ever there is a file(or files) created in this directory, (after the file is completely copied to the /eth/Src/ directory) I need to zip all the files and mail the files to a particular email id through the SMTP configured in our server, after the email is succesfully sent , I need to move the file to a archive directory.

I am familiar with send mail in unix through SMTP, what I need is the shell script should keep on checking the /eth/Src/ directory 24/7 and when ever files is created it has to zip and send the mail. please give me some idea on how to acheive this part.

Best Regards,
Wang

The proper way to do this is for the sending process to create them in some other directory on the same partition. Once it finishes sending, it should move them into /etc/Src, where they will appear instantly and whole. You'll never catch a file halfway through uploading.

Is this possible? Or some other sort of signal from the sender? Without that, it's impossible to tell when a file is actually finished. Only the sender really knows that.

In absence of hash/actual file size/record count, One possible way to detect complete download is to check size of downloading file in every 2mins, once the file size stop growing you can assume the file is downloaded.

Corona688 hit it on the head. It's best to have the process create it elsewhere then move it. If that can't happen, then you could try monitoring the process to see when it completes (i'm assuming it's a job that runs at intervals). Once the job has completed, then check for the files, tar and ship them off.
