First you don't need the 'cat' here. It serves no useful purpose. I see a lot of people do that as a bad habit. Second I think you want to squeeze repeated newlines and then translate them to spaces. tr -s "\012" " " < file If you need to restore a single final newline, we translated them to spaces here, then we can use echo. tr -s "\012" " " < file ; echo I am only using "\012" here since '\n' is shell specific but "\012" works on older more traditional unix systems. If '\n' works for you then I would keep using it.
