If you just want to run an Octave m-file script from the shell, then add the 
line below to the top of your file (depending upon where your octave is 
installed, this line may need to change).

        #! /opt/local/bin/octave -qf

Thus, your Plot1.m file's contents would be ....

~~~~~~~~~~~
#! /usr/bin/octave -qf
clear all; 
close all;
a=dlmread('file1');aT=a(:,1);aV=a(:,2);
figure 
plot(aT,aV);
print -dpdf Attempt.pdf
~~~~~~~~~~~

Then change the permissions ....

        chmod 755 Plot1.m

... and run the script.
