what is wget?

CentOS wget is a free tool for automatically downloading files from the web.

• It supports HTTP, HTTPS and FTP protocols and can use HTTP proxy.
• The so-called automatic download means that CentOS wget can be executed in the background after the user logs out of the system.
• This means that you can log into the system, start the CentOS wget download task, and then log out of the system.
• CentOS wget will execute in the background until the task is complete.
• Compared to most other browsers, downloading large amounts of data requires constant user involvement and less hassle.

recursive download

Wget can follow link-related downloads on HTML pages to create local versions of remote servers, completely rebuilding the original website's directory structure.This is also known as "recursive download".

When downloading recursively, wget follows the robots exclusion criteria (/robots.txt). Wget can be converted to point to a local file and download it for offline browsing.

wget is very stable

It has strong adaptability when the bandwidth is very narrow and the network is unstable.

• If due to network failure, wget will keep trying to download the entire file.
• If the server interrupts the download process, it will reconnect to the server and continue downloading from where it left off.
• This is useful for downloading large files on servers with limited download link times.
