[SOLVED] to download files randomly from website

how to download files randomly from website (http://localhost/log/) using bash script.

the url contains 100 files like shown below:

http://localhost/log/log01.log

http://localhost/log/log02.log

... log100.log

For example; if user enters the number 4, then the script should download 4 files randomly.

during download process the script should output the download result as shown below:

Downloading [filename], with the file name [filename and extension], with a file size of [file size and metric]
