How can I replace a newline (\n) using sed?

stackoverflow (hdorio)

Fast answer:

sed ':a;N;$!ba;s/\n/ /g' file
  1. :a create a label 'a'
  2. N append the next line to the pattern space
  3. $! if not the last line, ba branch (go to) label 'a'
  4. s substitute, /\n/ regex for new line, / / by a space, /g global match (as many times as it can)
