Check ftp return codes from Unix script

Question

I am currently creating a nightly job that calls a Unix script, which in turn creates and transfers a file using ftp. I would like to check all possible return codes. The manual page for ftpdoes not contain return codes. Does anyone know where to find the list? Anyone with experience? We have other scripts that grep for specific return lines in the log, and they send an email in error. However, they often skip unexpected codes. Then I put the reason in the log and email.

Answer 1

The command ftpreturns nothing but zero in most of the implementations I have implemented.

It is much better to handle three-digit codes in a log - and if you are sending a binary file, you can verify that the bytes sent were correct.

Three-digit codes are called “serial codes,” and the list can be found here.

Answer 2

I wrote a script to transfer only one file at a time and in this script use grepto verify the message 226 Transfer complete. If he finds it, grepreturns 0.

ftp -niv < "$2"_ftp.tmp | grep "^226 "

Answer 9

Why not just save all the output from the command to the log file, and then check the return code from the command and, if it is not 0, send the log file in an email?
