FTP Error Message

Hello All

I have below code snippet

/usr/bin/ftp -niv $ftphost 1>&2 >> $upload_log <<EndFtp
  quote user $ftp_user
  quote pass $ftp_pass
  cd $ftp_dir
  put $upload_file

When i pass a wrong ftphost as a paramater, output is "ftp: abc.net: Name or service not known". (abc.net is the wrong server name which i have passed ). But this output is not being redirected to upload_log file instead it is getting dispalyed on the terminal. If incorrect credentials are passed, then they are redirected to upload_log file.

Is there any way to check the status of the transfer. If transfer fails, i wish to send an email. But how can i check whether transfer failed or not. As far as i know, exit status is always 0 from ftp whether it fails to transfer or not. Please provide me a solution on this.

Appreciate your help in advance

The usual and recommended form for logs is "command arg1 arg2 arg3 >> log_file 2>&1". The order is important, as you can redirect a cross between what was stdout media and stderr media. "1>%2" is same as ">&2", says put stdout to the stderr device (tty?) first, and then you try to direct it to a file (who wins?) I trust you are in the right local dir, as you did no lcd, perhaps did a cd outside ftp above?

Redirection was working now.

But is there any way find out whether FTP worked successfully or failed during file transfer. Can we check the status of FTP Transfer.

I believe ftp exit( not zero) if problem, but the man page is silent.

I like to find an end to end sort of solution, like listing files pushed using ftp ls or pulled using shell ls -l, making sure files pulled are not empty, are complete (how to tell depends on file type).
