dir sort by date

[Rajesh Rajaram]

I have a bunch of files in a directory which are not named in any order. So when I use dir function, I get them in some order. But I would like to read those files in the order of its datenum. Is there an option in dir or any other function which can achieve this task.

Thanks in advance
Rajesh

You can sort the names by date:

% Data
D = dir;

% Engine
S = [D(:).datenum].'; % you may want to eliminate . and .. first.
[S,S] = sort(S);
S = {D(S).name} % Cell array of names in order by datenum.

Is this what you want?
A = dir;
[~,idx] = sort([A.datenum]);
then idx is the list from oldest to newest.
I.e.
oldest = A(idx(1))
newest = A(idx(end))

Thanks a lot. I ended up doing something very similar with the sort function. I was just hoping that there would be a more elegant option with the dir function or something.

But thanks a lot for your suggestion. I really appreciate your effort to solve my querry.

You could write your own wrapper 'dir' function that masks this behind the scenes work to make it elegant:

function out = ddir;
A = dir
... %rest of engine
end
