Shell-scripts,ftp Automated upload script, loop until upload is successful

Scripting Features:

The script is run by a timed scheduled task, and the specified file is uploaded periodically.

Before writing this script, sometimes the network is unstable, always upload failed. Write a loop to pass, but do not know how to get the error state of the FTP return, later Niang to the FTP can be run error log records written to the file, because this point from sharing. So now let's share the whole script and give you a clue.

By detecting this error day record and returning the status, go through the loop to upload the specified file and append the script to run the log records, so as to keep track of the script running.
