Subject: Some basic Ruby questions

Hi!

I am writing a gallery maker (HTML) in ruby and could need some help..

I already know how to write to files.
What I don't know is following:

How can i execute some native commands in Ruby? (For example ls | grep "jpg" > 
test.txt)

What I am planning  to do is executing this linux command, so that all
image files names get stored in a local file on the HD.
And after that i want to read the filenames in my ruby application one by
one, cause each file has an own line in this output file.

So, it should look like this:

def pictureMethod
	executeNativeCommand("ls | grep \"jpg\" > pictures.txt")
	pictureFile = File.open("pictures.txt","r")
	while(pictureFile.hasMoreLines)
		array.attach(pictureFile.actualLine)
		pictureFile.goOneLineDown
	end
end

I don't know the Ruby syntax that's why I wrote it in kind of "spoken code":-)

Hope someone can help me out,

Thanks in advance, Benjamin
