今天同事问我一个问题，在Linux 下访问FTP，并将文件上传上去。 我之前一直是用WinSCP工具的。 先将文件从linux copy到windows下，然后在传到ftp上。google 一下。 方法也比较简单。 这里只讨论通过终端来连接，因为也可以通过IE 或者其他工具。
1. Linux 终端连接FTP
[oracle@Dave ~]$ ftp 10.85.7.97
Connected to 10.85.7.97.
220 Serv-U FTP Server v6.4 for WinSock ready...
500 'AUTH': command not understood.
500 'AUTH': command not understood.
KERBEROS_V4 rejected as an authentication type
Name (10.85.7.97:oracle): super
331 User name okay, need password.
Password: -- Linux 的密码是不回显的
230 User logged in, proceed.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp>
如果FTP 允许匿名用户，那么用户名要输入anonymous,密码任意。 不能直接敲回车。
2. 查看FTP 命令
ftp> ?
Commands may be abbreviated. Commands are:
! cr mdir proxy send
$ delete mget sendport site
account debug mkdir put size
append dir mls pwd status
ascii disconnect mode quit struct
bell form modtime quote system
binary get mput recv sunique
bye glob newer reget tenex
case hash nmap rstatus trace
ccc help nlist rhelp type
cd idle ntrans rename user
cdup image open reset umask
chmod lcd passive restart verbose
clear ls private rmdir ?
close macdef prompt runique
cprotect mdelete protect safe
可以通过help command 查看每个命令的说明
ftp> help put
put send one file
ftp> help mput
mput send multiple files
3. 上传文件
Put命令：格式：put local-file [remote-file] 将一个文件上传到ftp
Mput命令：格式：mput local-files 将本地主机中一批文件传送至远端主机.
注意：mput命令只能将当前本地目录下的文件上传到FTP上的当前目录。比如，在 /root/dave下运行的ftp命令，则只有在/root/dave下的文件linux才会上传到服务器上的当前目录下。
Put 代码示例：
ftp> pwd -- 显示FTP上当前路径
257 "/" is current directory.
ftp> ls -- 显示当前目录下的文件

4. 下载文件
同样也有2个命令： get 和 mget。 Mget 用户批量下载。
格式：get [remote-file] [local-file]
mget [remote-files]
同样，mget 是将文件下载到本地的当前目录下。
Get 示例：
ftp> get /test/SFDBA /home/SFDBA
local: /home/SFDBA remote: /test/SFDBA
local: /home/SFDBA: Permission denied --Linux对权限控制的很严格，下载的时候是否有对应文件夹的写权限
ftp> get /test/SFDBA /home/oracle/SFDBA
local: /home/oracle/SFDBA remote: /test/SFDBA
227 Entering Passive Mode (10,85,7,97,17,0)
150 Opening BINARY mode data connection for SFDBA (5 Bytes).
226 Transfer complete.

ftp> !
[oracle@Dave bdump]$ cd /home/oracle/
[oracle@Dave ~]$ ls
Dave DBA dead.letter scripts SFDBA sqlnet.log
Mget 示例：
ftp> ls
227 Entering Passive Mode (10,85,7,97,17,10)

226 Transfer complete.
ftp> mget *
mget DBA? -- 每个文件都要确认， 按回车即可
227 Entering Passive Mode (10,85,7,97,17,12)

227 Entering Passive Mode (10,85,7,97,17,13)
150 Opening BINARY mode data connection for Dave (12 Bytes).
226 Transfer complete.
12 bytes received in 8.3e-05 seconds (1.4e+02 Kbytes/s)
mget SFDBA?

150 Opening BINARY mode data connection for SFDBA (5 Bytes).
226 Transfer complete.

ftp> !
[oracle@Dave ~]$ ls
Dave DBA dead.letter scripts SFDBA sqlnet.log
说明的地方：FTP 当前目录下的文件下载到本地的当前目录。
5. 断开FTP 连接
Bye命令或者quit命令：中断与服务器的连接。
ftp> bye
221 Goodbye!
以上只是Linux 终端访问ftp及上传下载的几个简单示例。 不过一般这几个应该够用了。其他功能感兴趣的自己研究。
