using sed

I'm trying to use sed to append "/0.0.0.0" to the end of each line in a file

sed -i 's;$;/0.0.0.0;g' file.txt

problem is most of the time, "/0.0.0.0" is made as a new line after the existing ones, instead of being appended to the ends of the lines

so instead of:
text/0.0.0.0

I get:
text
/0.0.0.0

In well-written tools, yes. That and info.

's_\(.*\).$_\1/0.0.0.0_'

Your analogy is broken, anyway, because the documentation is there and it's great.
