How to read lines of a file in Ruby

Question

I was trying to use the following code to read lines from a file. But when reading a file, the contents are all in one line:

line_num=0
File.open(\'xxx.txt\'         


        

Answer 1

It is because of the endlines in each lines. Use the chomp method in ruby to delete the endline '\n' or 'r' at the end.

line_num=0
File.open('xxx.txt').each do |line|
  print "#{line_num += 1} #{line.chomp}"
end
