Creating a file with a single space and no newline

Question

For testing purposes I am trying to create a file that only contains a single space character. However it seems most methods I use add a new line at the end. I've tried using vi and nano for editing.

Also tried echo " " > file but nothing so far

Answer 1

This will do it:

echo -n " " > file

The -n option suppresses the (default) newline.

If your system's implementation of echo does not recognize the -n option, then another alternative is:

printf " " > file
