Top Forums Shell Programming and Scripting How to check if downloading of a file is completed? Post 302989105 by Don Cragun on Sunday 8th of January 2017 03:01:47 AM

Let us propose that your 3rd party send you a zip file named file.zip (as they are doing now) and after they have sent you file.zip they then send you a file named file.checksum containing the checksum for file.zip. I am suggesting that instead of trying to figure out when file.zip is complete by trying to determine when it has stopped growing, you instead just watch for non-zero length files with names ending in .checksum. For each non-zero length file.checksum you find you will know that you have a complete corresponding file.zip and you can verify that it was received correctly by comparing the contents of file.checksum to the checksum of the file file.zip.
