Can you please tell, how to call external program in D.

Example: in C, one can do this:

I want to call an external program (e.g. ls or date) in D.


Thanks

This function should do for many tasks:


http://dlang.org/phobos/std_process.html#shell

string shell(string cmd);
     Runs cmd in a shell and returns its standard output. If the 
process could not be started or exits with an error code, throws 
an exception.

Or maybe this one:
http://dlang.org/phobos/std_stdio.html#popen

(also search that page for the other popen, which calls the C 
function without the need for a File struct)

Generally, anything you can do in C, you can also do in D by 
calling the C functions directly.

This is out of subject but for ls and date, you might want to get the 
informations directly in D.
