Executing a .m file from the Linux command line

Question

I have some code in a file named Demo-3.m, It can be evaluated in Mathematica 9. The final expression in the file is

Export[NotebookDirectory[] <> "fintempimg.jpg", fintempimg];

How can I execute Demo-3.m in Linux using the command-line? Please give me a solution with an example.

I think you can use script to do this, like math -script file.m. Here has very useful step by step detail.
Oh my god!! thanks for @xslittlegrass solution, it can work :)

As xslittlegrass posted in a comment to the question, the file Demo-3.m can be run on Linux by issuing

math -script Demo-3.m

at the command line.

More information on Mathematica scripting can be found here.
