linux - 使用wget下载文件
支持http, https, ftp协议进行下载

wget -P /mnt/iso http://mirrors.mit.edu/centos/7/isos/x86_64/CentOS-7-x86_64-Minimal-1804.iso
4. 限制文件下载速度
wget --limit-rate=1m https://dl.google.com/go/go1.10.3.linux-amd64.tar.gz
5. 恢复一个中断的下载
wget -c http://releases.ubuntu.com/18.04/ubuntu-18.04-live-server-amd64.iso
6. 使下载在后台运行
wget -b https://download.opensuse.org/tumbleweed/iso/openSUSE-Tumbleweed-DVD-x86_64-Current.iso
7. 设置用户代理
wget --user-agent="Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101 Firefox/60.0" http://wget-forbidden.com/
