Copyfile without overwriting

How can I copy the content of a *.m file in another. I used copyfile('1.m','2.m') but with this command the content of 2.m will be overwriten by the content of 1.m.
Ex: 1.m content: test1; 2.m content: test 2. I am expecting to get after using copyfile the content of 2.m like: test 2, test1.
I also used the next lines but it is not looking ok.. % fid = fopen('first.m'); % F= fread(fid, '*char')'; % fclose(fid);

I don't think you can do that with copyfile. You can do it with fopen, but you need to open it with option 'a', and then append the content you want.
Here is an example
fid1 = fopen('1.m','r');
fid2 = fopen('2.m','a');
tline = fgetl(fid1);
if ~ischar(tline), break, end

You could use fwrite, or fprintf to write to the end of the file, fgetl would also be your friend.
