Remove newlines from output

grep . filename
Remove newlines from output. One character shorter than awk /./ filename and doesn't use a superfluous cat. To be fair though, I'm pretty sure fraktil was thinking being able to nuke newlines from any command is much more useful than just from one file.

What Others Think

You shortened the command, yes. What your command does though is remove duplicate newlines such that "Hello\n\n123" becomes "Hello\n123". If you were to truly "remove newlines from output" then "Hello123" would result and you would have one long string. But what I think you really want is to remove blank lines, which may even have extra whitespace, so use this (http://regex.info) : grep -v -e "^\s*$" filename If you really mean "remove newlines from output" then you could use: tr -d "\n" <filename
