| wget is a free tool that automatically downloads files from the Internet. It supports downloading through the three most common TCP/IP protocols: HTTP, HTTPS, and FTP, and can use HTTP proxy. The name "wget" comes from the combination of "World Wide Web" and "get". This article explains in detail the use of wget parameters and usage. I hope it will be helpful for everyone to understand the use of wget. |
What does it mean to automatically download files? In fact, it means: wget can be executed in the background after the user exits the system. This means that you can log in to the system, start a wget download task, and then exit the system. Wget will execute in the background until the task is completed. Compared with most other browsers that require continuous user participation when downloading large amounts of data, this saves a lot of time. Big trouble. Then let’s take a look at the specific usage.
