mac 终端 使用ftp命令

Mac下使用命令行登陆ftp

 

最近使用forklift下载服务器pureftp上的东西，总是断断续续的，经常下载到99%然后显示下载失败，非常不舒服！原以为是forklift的问题，换了transmit发现同样有这样的现象。看来是ftp服务器搭的有问题~~不过因为用的不多，目前懒的解决了，暂时用Mac的终端命令来用着。其实效率也是蛮高的哦=。=

默认的本地目录是home。 输入help即可获得所有命令的帮助。

1. 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
   

2. 浏览文件

   命令和Windows、Linux的命令基本相同

    ftp> cd Documents
    ftp> ls		
    ftp> dir
   

3. 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
   

4. 断开连接

   bye：中断与服务器的连接。

    ftp> bye
   

5. 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
    newer – only get a file if it’s newer (great for scripting synchronizations)
    nmap – use positional parameters to set filenames
    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

最后有一个问题，为什么老是有不明的人/机器想登陆我的FTP？= =不过自己也是只有使用的时候才会开。
