如果你是一名 Linux 服务器管理员可能经常会使用到 wget 这个下面命令，对了，这是一个开源 GNU wget 命令行，下载管理器，一个支持HTTP和FTP，HTTPS协议下载器。新版本详细变化：[list]
[]Add wget-udeb to ship wget as alternative to busybox wget
[]Build-Depend on libssl-dev instead of libgnutls28-dev
[]Pass –with-ssl=openssl; there’s no udeb for gnutls
[]Add a second build pass for the udeb, so we can build with -Os and without libidn
[]Use dh_autotools-dev instead of custom config.{sub,guess} copy
[]No longer create local symbolic links by default.
[]Use libpsl for verifying cookie domains
[]Default progress bar output changed
[]Introduce –show-progress to force display the progress bar
[]Introduce –no-config. The wgetrc files will not be read
[]Introduce –start-pos to allow starting downloads from a specified position
[]Fix a problem with ISA Server Proxy and keep-alive connections
[/list]安装方法，因为没有PPA，用户需要自行编译，命令如下：sudo apt-get update
sudo apt-get build-dep wget
wget http://ftp.gnu.org/gnu/wget/wget-1.16.tar.gz
tar -xvf wget-1.16.tar.gz
cd wget-1.16/
./configure --with-ssl=openssl --prefix=/opt/wget
make
sudo make install
sudo ln -s /opt/wget /usr/bin/wget下载 wget 1.16，移除文件夹就可以了sudo rm -r /opt/wget /usr/bin/wget
