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.
