How to copy a file in the same path with a different name?

Well you just need to use curly braces, {}, to make it happen:

What you usually MIGHT do:

cp /usr/local/share/lib/sample.conf /usr/local/share/lib/settings.conf

You can take the smart path btw:

cp /usr/local/share/lib/{sample,settings}.conf

NOTE: if suffix of both files are different you can put that inside of curly braces too.
