Hi,

is there a simpler/more idiomatic way to append/join the contents of  
multiple text files into 1 file?

this works, but i’m trying to see if there are more succinct methods.  
thanks!

mynewfile = File.new(‘C:\mynewfile.txt’, ‘w’)  
@myfilenames.each do |mfn|  
File.open(’#{mfn}.txt’) do |file|  
file.each\_line {|line| mynewfile.puts(line)}  
end  
end  
mynewfile.close

This should work:

File.open(‘C:\mynewfile.txt’,‘w’) do |f|  
@myfilenames.each do |mfn|  
f.puts(File.read(mfn))  
end  
end

I hope this helps
