　　1. Wget

Wget is a very common command line download tool. most Linux releases contain this tool by default. If not installed, you can download the latest version in http://www.gnu.org/software/wget/wget.html and compile the installation using the following command:

◆-T: number of attempts to connect. how many attempts will be made when Wget cannot establish a connection with the server.

In addition, Wget can download the entire site, such as downloading the entire Man manual center of the http://man.chinaunix.net. Enter the following command: # wget-r-p-np-k http://man.chinaunix.net where the-r parameter refers to recursive download, -p refers to downloading all files, slices, and other files required to display the complete web page.-np refers to not searching the upper-level directory, and-k refers to converting absolute links into relative links.

　　III. Curl

Curl is also a good command line download tool in Linux, which is small and fast. The only drawback is that it does not support multi-thread download. Download the latest version at http://curl.haxx.se/download/curl-7.14.0.tar.gz. After the download, you can use the following command to compile and install:

Typical Curl downloads are as follows: # curl-O http: // 10.1.27.10 /~ Kennycx/tools/lumaqq_2004-linux_gtk2_x86_with_jre.tar.gz uses Curl to download a file and save it to the current directory.

In addition, although Curl does not support multi-threaded download, it can download multiple files at the same time or a part of the downloaded files. you can use the following command to achieve this:

# Curl-r 0-199 http://www.netscape.com/get the first 200 bytes of the file.

You can easily download Curl from common proxies. the specific operations are as follows:

# Curl-x 10.1.27.10: 1022 the ftp://ftp.funet.fi/README uses the proxy server with the proxy address 10.1.27.10 Port 1022 to download a file.

# Curl-U user: passwd-x 10.1.27.10: 1022 ftp://ftp.funet.fi/README if the proxy server requires special authentication, enter a valid account and password at user: passwd.
