如何在Linux 下訪問FTP，並將文件上傳上去。 我之前一直是用WinSCP工具的。 先將文件從linux copy到windows下，然後在傳到ftp上。
google 一下。 方法也比較簡單。
這裏只討論通過終端來連接，因爲也可以通過IE 或者其他工具。
1. Linux 終端連接FTP
[oracle@Dave
~]$ ftp 10.85.7.97 （默認端口21時可用，否則出現 ftp:connect:Connection refused錯誤。）
非默認端口時使用：ftp
ip port
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 的密碼是不回顯的
230 User logged in, proceed.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp>
如果FTP 允許匿名用戶，那麼用戶名要輸入anonymous,密碼任意。 不能直接敲回車。
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
可以通過help command
查看每個命令的說明
ftp> help put
put send one file
ftp> help mput
mput send multiple files
3. 上傳文件
Put命令：格式：put local-file [remote-file]
將一個文件上傳到ftp
Mput命令：格式：mput local-files
將本地主機中一批文件傳送至遠端主機.
注意：mput命令只能將當前本地目錄下的文件上傳到FTP上的當前目錄。比如，在
/root/dave下運行的ftp命令，則只有在/root/dave下的文件linux纔會上傳到服務器上的當前目錄下。
Put 代碼示例：
ftp> pwd -- 顯示FTP上當前路徑
257 "/" is current directory.
ftp> ls -- 顯示當前目錄下的文件

4. 下載文件
同樣也有2個命令： get 和 mget。 Mget 用戶批量下載。
格式：get [remote-file] [local-file]
mget [remote-files]
同樣，mget 是將文件下載到本地的當前目錄下。
Get 示例：
ftp> get /test/SFDBA /home/SFDBA
local: /home/SFDBA remote: /test/SFDBA
local: /home/SFDBA: Permission denied --Linux對權限控制的很嚴格，下載的時候是否有對應文件夾的寫權限
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.
5 bytes received in 6.2e-05 seconds (79 Kbytes/s)
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)
150 Opening ASCII mode data connection for /bin/ls.
drw-rw-rw- 1 user group 0 Aug 17 17:38 .

-rw-rw-rw- 1 user group 12 Aug 17 17:38 Dave
-rw-rw-rw- 1 user group 5 Aug 17 17:11 SFDBA
226 Transfer complete.
ftp>mget *
mget DBA? -- 每個文件都要確認， 按回車即可
227 Entering Passive Mode (10,85,7,97,17,12)
150 Opening BINARY mode data connection for DBA (5 Bytes).
226 Transfer complete.
5 bytes received in 8.1e-05 seconds (60 Kbytes/s)
mget Dave?
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?
227 Entering Passive Mode (10,85,7,97,17,14)
150 Opening BINARY mode data connection for SFDBA (5 Bytes).
226 Transfer complete.
5 bytes received in 9e-05 seconds (54 Kbytes/s)
ftp> !
[oracle@Dave ~]$ ls
Dave DBA dead.letter scripts SFDBA sqlnet.log
說明的地方：FTP 當前目錄下的文件下載到本地的當前目錄。
5. 斷開FTP 連接
Bye命令或者quit命令：中斷與服務器的連接。
ftp> bye
221 Goodbye!
以上只是Linux 終端訪問ftp及上傳下載的幾個簡單示例。 不過一般這幾個應該夠用了。其他功能感興趣的自己研究。
