Retry upon FTP failure

I am using the following code in a C Shell script to transfer files to a remote server:
ftp -n <<DO_FTP1
quote user $user_name
quote pass $password
put $js_file_name
put $FinalZipFile

This code works great except on those rare occasions when the remote server is down or, for whatever reason, fails. This causes my code to fail and makes my already tense users angry. This code runs on both Unix and Linux. Is there a way to force a retry after a specified time period if there is a failure of the ftp command? Also, is there a way to make the hash mark print at something other than every 8192 bytes (something more like every GB)?

Save the output of the script into a log file, and examine the log file afterwards.
ftp <<DO_FTP1 >abc.log

Sorry - that didn't work. The script stalls at the re-direction and just sits there. I have to ctrl-c to end it. Thanks anyway.

Add a line just before the quit statement in the ftp input to get a file from the remote machine,
If the file does not exist on your local system after the ftp job has completed, then you should investigate.
rm job.complete
ftp -n xxxxx <<EOF
get job.complete
if [ -r job.complete ]
exit 0

How does job.complete get on the remote server from which you are trying to retrieve it in the first place?

Either put it there yourself, or ask the admin there to do it for you, or choose any file that will always exist on the remote server.

Is there not a way to have ftp give an exit status that can be retrieved to determine if it succeeded or failed?
