Reg IO class

Hi,
Should we close the file after reading it?

Please see the code below…

data = IO.readlines(“test.txt”,“r”)
diskfile = File.open(“test.xml”,“w+”)
data.each do |line|
line.chomp!
diskfile.puts(line) if line.length>0
end

It is working fine, even without closing the file(diskfile.close). Can
someone suggest me. Does the file close automatically or not?

Thanks in advance

Yes, of course.

In the first line yes, in the second chunk, no. This can be easily
fixed by using the block form of File.open.
