连接ftp服务器
man ftp 可以看到有这些信息。
NAME
ftp -- Internet file transfer program
SYNOPSIS
ftp [-46AadefginpRtvV] [-N netrc] [-o output] [-P port] [-q quittime]
[-s srcaddr] [-r retry] [-T dir,max[,inc]] [[user@]host [port]]
[[user@]host:[path][/]] [file:///path]
[ftp://[user[:password]@]host[:port]/path[/][;type=X]]
[http://[user[:password]@]host[:port]/path] [...]
ftp -u URL file [...]
连接服务器的话基本上就用到上面的讯息了。原本没有看man手册，一直使用
ftp user@xxx.com port
每次都要输入密码。后来还是用了下面这个更加简单的
ftp ftp://User:Passwd@xxx.com:port
浏览文件
命令和Windows、Linux的命令基本相同
ftp> cd Documents
ftp> ls
ftp> dir
下载上传文件
put filename - Upload a file to the server
get filename - Download a file from the server
mput filename - Put multiple files on the server
mget filename - Get multiple files on the server
断开连接
bye：中断与服务器的连接。
ftp> bye
大部分的命令如下，可敲入man ftp获得
ls – list the contents of a directory on the FTP server
cd – change the working directory on the FTP server
pwd – show the current directory on the FTP server
get – download files from the FTP server
put – upload files to the FTP server
account – include a password with your login information
bye – terminate an ftp session and close ftp (or use disconnect to simply terminate a session)
bell – make a cute sound after each file transfer is done
chmod – change permissions
delete – your guess is as good as mine (OK, you got me, it’s to delete a file off the server)
glob – enable globbing
hash – only functional in Amsterdam
help – get help
lpwd – print the local working directory for transfers
mkdir – create folders on the FTP server
rmdir – delete folders from the FTP server

passive – use FTP passive mode
prompt – allows the use of letters to automate answers to prompts
rate – limit the speed of an upload or download
关于ftp，你甚至还可以写脚本进行文件操作，比如
#!/bin/bash
ftp -d krypted.com << ftpEnd
prompt
cd /Library/WebServer/Documents
put “*.html”
put “*.php”
cd /Library/WebServer/Documents
put “*.png”
quit
ftpEnd
#!/bin/bash
ftp -d krypted.com << ftpEnd
prompt
cd /My/Documents
get “*.doc”
quit
ftpEnd
在你的脚本中，可以使用以下几个字符获取一些特定的变量：
%/ – the current working directory of the FTP server
%M – the hostname of the FTP server
%m – the hostname only up to the .
%n – the username used for the FTP server
