How to prevent quote signs in File.readlines

For example 开发者_开发百科I have file file_name with such content:

Just some text,
nothing more

Then I run kind of this code:

lines = File.open(file_name, "r").readlines
# do something do with lines
File.open(file_name, "w").write(lines)

I'll get this text

"Just some text,"
"nothing more"

How to prevent " sign here? I want text without quotes. Thanks

If you are using ruby 1.9.2, Array#to_s works like Array#inspect. Try this instead (some style tweaks thrown in):

lines = File.readlines(file_name)
File.open(file_name, 'w') { |f| f.write(lines.join) }

If you are only concerned with the quotes enclosing each line

okay, let's try that again

lines.gsub(/^"|"$/, '')

should work
