Many times you need to download files from the internet, specifically when you want to automate a process or two. Here is where wget comes in handy. This is a standard tool on most Linux systems.
In some cases the server you want to download from does a couple of checks, so your automation fails. You can come by that by adding a couple of switches like:
wget --user-agent="Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36" --auth-no-challenge URL_OF_FILE_TO_DOWNLOAD
Sometimes: wget --user-agent="Mozilla"
