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!

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.
http://dlang.org/rdmd.html

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?

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>");
	}
}

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

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