提问by Pierre de LESPINAY
I have file containing a list of files separated by end of lines

file2
file3
I want to copy this list of files with FTP

How can I do that ? Do I have to write a script ?

You can turn your list of files into list of ftp commands easily enough:
您可以轻松地将文件列表转换为 ftp 命令列表：
(echo open hostname.host;
echo user username;
cat filelist | awk '{ print "put " ; }';
echo bye) > script.ftp
Then you can just run:
然后你可以运行：
ftp -s script.ftp
ftp -s script.ftp
Or possibly (with other versions of ftp)
或者可能（使用其他版本的 ftp）
ftp -n < script.ftp
ftp -n < script.ftp

Thanks for the very helpful example of how to feed a list of files to ftp. This worked beautifully for me.
感谢有关如何将文件列表提供给 ftp 的非常有用的示例。这对我来说效果很好。
After creating my ftp script in Linux (CentOs 5.5), I ran the script with:
在 Linux (CentOs 5.5) 中创建我的 ftp 脚本后，我使用以下命令运行脚本：
ftp –n < ../script.ftp
My script (with names changed to protect the innocent) starts with:
我的脚本（改名以保护无辜者）以以下内容开头：
open <ftpsite>
user <userid> <passwd>
cd <remote directory>
bin
prompt
get <file1>
get <file2>
And ends with:
并以：
get <filen-1>
get <filen>
bye

Something along these lines - the somecommanddepends on what you want to do - I don't get that from your question, sorry.
沿着这些路线的东西 - 这 somecommand取决于你想做什么 - 我没有从你的问题中得到这一点，抱歉。
#!/bin/bash
# Iterate through lines in file
for line in `cat file.txt`;do
#your ftp command here do something
somecommand $line
done
edit: If you really want to persue this route for multiple files (you shouldn't!), you can use the following command in place of somecommand $line:
编辑：如果你真的想为多个文件坚持这条路线（你不应该！），你可以使用以下命令代替somecommand $line：
ncftpput -m -u username -p password ftp.server.com /remote/folder $line
ncftpput propably also takes an arbitrary number of files to upload in one go, but I havn't checked it. Notice that this approach will connect and disconnect for every single file!
ncftpput 也可以一次性上传任意数量的文件，但我没有检查过。请注意，这种方法将连接和断开每个文件！
