bash + ftp：上传文件为空

Question

I have written a bash script to update a page on my company's website. Here's what I've got so far:

#!/bin/bash

ruby final_07.rb

HOST=ftp.website.com
USER=username
PASSWD=password

ftp -n -v $HOST <<EOF
user $USER $PASSWD
delete warehouse.html.old
rename warehouse.html warehouse.html.old
put warehouse.html warehouse.html

EOF

It runs the Ruby script just fine. It connects to the FTP just fine. It even renames the old file just fine. However, when it "uploads", I just get a file named 'warehouse.html' that is 0 bytes - it's totally empty. I checked, and the source file is fine. When I manually upload with FileZilla, it works just fine, too. So, what gives?

Here's the log from my terminal window:

john@starfire:~/code/ruby/idealm_db_parser/final$ ./update_script_02.sh
Connected to www.website.com.
220 FTP Service
Remote system type is UNIX.

250 Rename successful

200 PORT command successful
150 Opening BINARY mode data connection for warehouse.html
226 Transfer complete.
221 

Thanks in advance for any help. I'm running Ubuntu 10.10, if that helps.

Answer 1

You could try to

• switch to asci mode before you put your file
• use passive ftp mode for transfering the file

Answer 2

I think I got it sorted. I removed the lines:

delete warehouse.html.old
rename warehouse.html warehouse.html.old

and that seemed to do the trick. For some reason, apparently the script was zeroing the warehouse.html file on MY computer, then uploading that.

Thanks to everyone who helped, though.
