Removing carriage return/line feeds on multiple lines
I would like to remove carriage returns/line feeds in a text file, but in a specific cadence:
  • Read first line (Header Line 1), remove cr/lf at the end (replace it with a space ideally);
  • Read the next line (Line of Text 2), leave the cr/lf intact;
  • Read the next line, remove the cr/lf;
  • Read the next line (Header Line 2), remove cr/lf at the end (replace it with a space);
  • Read the next line (Line of Text 2), leave the cr/lf intact…

Here is my input data, in red of the cr/lf I would like deleted

Code:
Header Line 1 <cr/lf> ( replace with a space)
Line of Text 1<cr/lf>
<cr/lf> 
Header Line 2 <cr/lf> (replace with a space)
Line of Text 2<cr/lf>
<cr/lf>

What I would like to output

Header Line 1 Line of Text 1
Header Line 2 Line of Text 2

Being new to sed, I have managed to remove all the cr/lf’s but I just end up with a long string of text. I would live to preserve the cr/lfs that separate Header Line 1 Line of Text 1 from Header Line 2 Line of Text 2.

Thanks for your help!
