I'm not sure what problems you are having exactly, File.open can
receive a variable:

a = "file.txt"

File.open(File.join("home","jesus","temp",a), "w") do |f|
  #do your stuff
end

You can choose values for a and do the same stuff in different files.

BTW, as you mention cgi I assume this is going to be published on the
internet. I advise you to be careful about how you choose the files
for security reasons. For example, don't let the files be anywhere in
your filesystem or you might compromise your server.

Jesus.
