[Linux] Download the whole website.
Using 'wget' can download the website.
By default it will download to the current locaiton.
Normally, we want to custom the download location and download it in background.
Sometime, we might want to download from where we stop before.
-p --page-requisites This option causes Wget to download all the files that are necessary to properly display a given HTML page. This includes such things as inlined images, sounds, and referenced stylesheets.
-m --mirror Turn on options suitable for mirroring. This option turns on recursion and time-stamping, sets infinite recursion depth and keeps FTP directory listings. It is currently equivalent to -r -N -l inf -nr.
-b : in the background.
-c: continuse from where previous stops
-P ./download/ : custom the location.
