I'm trying to get the minecraft.jar file to execute , but the check box won't come up when I go to Properties > Permissions. I don't know much about the terminal and its commands so if someone could post a simple step by step solution on how to mark it that would be great.
People keep saying to use a chmod command but I have no idea what that is, so you are forewarned if I say "over my head".

The important part is in your message:
"The file '/home/mike/Downloads/minecraft.jar' is not marked as executable. If this was downloaded or copied from an untrusted source, it may be dangerous to run. For more details, read about the executable bit."
Command line
The command:
sudo chmod +x /home/mike/Downloads/minecraft.jar
will make it executable. Be sure to read the 2nd part of the message: make sure you got it from a trusted source.
GUI
If it is easier for you, you can also view the file with Nautilus and richt click it, open Properties, open the Permissions tab, and tick the box that says:
Execute: Allow executing file as a program.
Other
From a very reliable source I have been told you can also do:
java -jar /home/mike/Downloads/minecraft.jar
- Press Ctrl+Alt+T to open a terminal.
Navigate to the location of your file by inputting
cdcommand into the terminal Eg.cd /documents/, then enter the following:chmod +x yourfilename
To view if your changes had been saved enter the following ls -l in the terminal.
Other way to change your file to an executable is to right click the file, select Properties → Permisions and tick Allow execution of the file as a program.
Hope this helps. Also to execute the file you first have to be in the directory where it is located. For instance if your file is located in the Documents folder, you have to cd ("change directory") in to that directory and then do this: ./yourfile.c
This is how it will look:
root@root:~/Documents$ ./file.c

Assuming the file in question is in your $HOME (just move it with the GUI otherwise), open a terminal (that much should be easy :) then run this command:
Change
jarfile.jarto the actual name of the file in question of course. If that gives you an error, the file is probably not owned by your user, so try again withsudo:
