Linux终端访问FTP及上传下载⽂件
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
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
