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').each do |line|
print "#{line_num += 1} #{line}"
end
But this file prints each line separately.
I have to use stdin, like ruby my_prog.rb < file.txt
, where I can't assume what the line-ending character is that the file uses. How can I handle it?
Ruby does have a method for this:
File.readlines('foo').each do |line|
