Welcome to Linux!
Yup, the commands you were told to run were probably to be done from the command line (as it allows people to provide a concrete set of instructions that don't fall victim to things like the various file managers, and other graphical nuances).
Normally, a user on a Linux/UNIX/*BSD system does not have permission to write to any directory other than their own home directory (/home/
YOUR_USER_NAME). When you open up a terminal emulator (Konsole, Gnome-Terminal, Xterm, ..., etc.) type in the following commands, and please note that I am assuming you have the ZIP file in your home directory:
Code:
$ unzip alien_arena.zip
$ sudo mv alien_arena/ /usr/local/games/
Now, to make sure that /usr/local/games is in your $PATH variable; the $PATH
variable lets the shell know where to look for executable files.
$ echo $PATH | grep -i /usr/local/games
If that command does not return anything, then issue the following commands.
$ echo "export PATH=/usr/local/games:$PATH" >> ~/.bashrc
$ source ~/.bashrc
