Reading data matrix from text file in Julia

Question

I have text file which includes a matrix. I want to read it in julia as a matrix.

The text file is like:

0 0 0 0 0 0 0
1 0 0 0 0 0 0
1 0 0 0 0 0 1
1 0 0 0 1 1 0

In matlab you can do the following to create matrix M :

file='name.txt';
[M] = load(file);

How to do same thing in Julia?

1   0   0   0   0   0   1
1   0   0   0   1   1   0

julia> m = readdlm("/tmp/m.txt")
4x7 Array{Float64,2}:
 0.0  0.0  0.0  0.0  0.0  0.0  0.0
 1.0  0.0  0.0  0.0  0.0  0.0  0.0

you can `readdlm` into Julia without having to `cat` the file first. – amrods Feb 10 '16 at 16:32
