Correct me if I'm wrong, but it looks like it's there. ???

In

cgi.p{
Dir["*.*"].each{ |f|
"huhu "
}
}

cgi.p is emitting the return value of

Dir["*.*"].each{ |f|
"huhu "
}

which is the set of file names, not the string "huhu "

Try this as a simple script to see this:

puts Dir["*.*"].each{ |f| "huhu " }


You may want


Dir["*.*"].each{ |f|
cgi.p{ "huhu " }
}

Or something like that.

James
