linux中wget命令的使用方法

wget工具体积小,功能完善，支持断点下载，支持FTP和HTTP下载方式，支持代理服务器,设置方便简单。

下载单个文件:

wget http://www.baidu.com/example.zip 

下载多个文件:

首先，保存一份下载链接文件 
cat > filelist.txt 
url1 
url2 
url3 
url4 
接着使用这个文件和参数-i下载 
wget -i filelist.txt 

重命名下载的文件:

wget -O test.zip http://www.baidu.com/example.zip  

限速下载

wget –limit-rate=300k http://www.baidu.com/example.zip 

断点续传:

wget -c http://www.baidu.com/example.zip 

后台下载:

wget -b http://www.baidu.com/example.zip 
>Continuing in background, pid 23400. 
>Output will be written to `wget-log’. 
可以通过命令tail -f wget-log查看下载进度

查看下载连接是否正确:

wget –spider URL 
如果下载链接正确，将会显示 :
wget –spider URL 
Spider mode enabled. Check if remote file exists. 
HTTP request sent, awaiting response… 200 OK 
Length: unspecified [text/html] 
Remote file exists and could contain further links, 
but recursion is disabled — not retrieving. 
如果下载链接错误，将会显示 :
wget –spider url 
Spider mode enabled. Check if remote file exists. 
HTTP request sent, awaiting response… 404 Not Found 
Remote file does not exist — broken link!!!
