Remove newlines from output

Pipe any output to "grep ." and blank lines will not be printed.

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.

awk /./ filename

?Cat and grep? You can use only grep ("grep \. filename"). Better option is awk.

grep -v "^$" filename > newfilename

The ^$ within the quotes is a regular expression: ^=beginning of line, $=end of line, with no characters between.

sed '/^$/d' file >newfile

Know a better way?

If you can do better, submit your command here.

What others think

Useless use of cat.
