Wget [options] [URL-list]

-L specified ). For the FTP host, this parameter means to download all the files in the directory specified by the URL, recursively
Method and
The HTTP host is similar.

-N timestamp: this parameter specifies that wget only downloads the updated files, that is
Of
Files with the same length as the last modification date will not be downloaded.

-M image: equivalent to using both the-r and-N parameters.

-L sets the recursive level. the default value is 5. -L1 is equivalent to non-recursion.-l0 is infinite recursion. note,
When delivered
When the depth increases, the number of files will increase exponentially.

-T sets the number of retries. When the connection is interrupted (or times out), wget tries to reconnect. For example
Result
If-t0 is specified, the number of retries is set to an infinite number.
