I have an issue with installing a Minecraft server. When I use the command
wget -O minecraft_server.jar https://s3.amazonaws.com/Minecraft.Download/versions/1.7.9/minecraft_server.1.7.9.jar
It will open the wget --help menu and it will not download the jar. When I open the link in my browser it will download it so it's not the link.
That's odd. Try wrapping the URL in double quotes:
wget -O minecraft_server.jar "https://s3.amazonaws.com/Minecraft.Download/versions/1.7.9/minecraft_server.1.7.9.jar"
Does that work?
That kinda worked, now I get the following message:

You're missing a "dot" between "server" and "1.7.9":
minecraft_server.1.7.9.jar
For the most recent version, I simply typed:
wget https://s3.amazonaws.com/Minecraft.Download/versions/1.8.1/minecraft_server.1.8.1.jar
Also, to paste into Putty (if you're using that), you simply copy the text like normal and then right-click into the putty console.
I wrote the minecraft tutorial here and checked each step myself if you need any other help.
