推荐答案

您真的应该使用SSH / SCP / SFTP此，而不是FTP。 SSH / SCP具有作为更安全的，并与公共/专用密钥，这使得它在没有用户名或密码运行工作的好处。

You really should use SSH/SCP/SFTP for this rather than FTP. SSH/SCP have the benefits of being more secure and working with public/private keys which allows it to run without a username or password.

您可以发送一个文件：

scp <file to upload> <username>@<hostname>:<destination path>

或者整个目录：

scp -r <directory to upload> <username>@<hostname>:<destination path>

有关设置键和移动文件到rsync的服务器，如果你有很多的文件移动，或者如果你有时会得到一组随机文件中只是一个新的文件，采取了这是有用的详细信息看一下：

For more details on setting up keys and moving files to the server with RSYNC, which is useful if you have a lot of files to move, or if you sometimes get just one new file among a set of random files, take a look at:

您也可以ssh方式连接到服务器后，执行一个命令：

You can also execute a single command after sshing into a server:

从男人SSH

SSH [...剪断...]主机名[命令]如果指定命令，它是
  远程主机，而不是一个登录shell上执行。

ssh [...snipped...] hostname [command] If command is specified, it is executed on the remote host instead of a login shell.

那么，一个例子命令是：

So, an example command is:

ssh [e-mail] bunzip file_just_sent.bz2

如果你可以用与键SFTP获得安全连接的好处，也有我用来执行命令两个技巧。

If you can use SFTP with keys to gain the benefit of a secured connection, there are two tricks I've used to execute commands.

首先，你可以使用命令传递回声和管

First, you can pass commands using echo and pipe

echo "put files*.xml" | sftp -p -i ~/.ssh/key_name [e-mail]

您也可以使用带有 -b 参数批处理文件：

You can also use a batchfile with the -b parameter:

sftp -b batchfile.txt ~/.ssh/key_name [e-mail]

如果你明白，FTP是不安全的，比较有限的，你真的真的想脚本吧...

If you understand that FTP is insecure and more limited and you really really want to script it...

在<一个有这个一个伟大的文章href=\"http://www.stratigery.com/scripting.ftp.html\">http://www.stratigery.com/scripting.ftp.html

#!/bin/sh
HOST='ftp.example.com'
USER='yourid'
PASSWD='yourpw'
FILE='file.txt'

ftp -n $HOST <<END_SCRIPT
quote USER $USER
quote PASS $PASSWD
put $FILE
quit
END_SCRIPT
exit 0

在-n到FTP确保命令不会尝试从当前终端获取密码。其他花哨的部分是使用定界符组成：＆LT;＆LT; END_SCRIPT 开始定界符，然后把相同的 END_SCRIPT 上由本身的行的开始结束定界符

The "-n" to ftp ensures that the command won't try to get the password from the current terminal. The other fancy part is the use of a heredoc: the <<END_SCRIPT starts the heredoc and then that exact same END_SCRIPT on the beginning of the line by itself ends the heredoc.
