Sorry. I wasn't very clear. Say I want to find all of the files 
that have a certain extension within a directory and process 
them somehow at the command line. How could I do that?


Have a look at the function dirEntries in std.file.

This is exactly what I was thinking.  Thanks so much for your
help!

Just a little something I made for you. Untested of course. But 
takes an argument from cli, which is a glob. Foreach file under 
current working directory, if its a file write out processing.


(I gave std.stdio an alias because std.file and std.stdio 
conflict for some symbols)


import std.file;
import stdio = std.stdio;

void main(string[] args) {
if (args.length == 2) {
foreach(entry; dirEntries(., args[1], SpanMode.Depth)) {
if (isDir(entry.name)) {
} else if (isFile(entry.name)) {
stdio.writeln(Processing  ~ entry.name);
}
}
} else {
stdio.writeln(Arguments: glob);
}
}

I am a little bit confused as to what you want.
There is a command line example at dlang.org, and there exists a program
(rdmd) that compiles several D files and runs them.

 I am trying to build some simple command line applications that I have
 written in python as a way to learn D. Can you give some examples for me?
 For instance, I think I remember once seeing somewhere in the documentation
 an example that took several D files and compiled them all by running some
 kind of system command.

 I much appreciate your help!
