[nmglug] cp ain't working

[a]

Good Day:

RRDp::start "/usr/local/rrdtool/bin/rrdtool"; is a file in Digitemp
README.

I wish to cp  /usr/bin/rrdtool (exacutable)
to /usr/local/bin/rrdtool/bin/rrdtool.

results:
a at a-desktop:~$ cp /usr/bin/rrdtool /usr/local/bin/rrdtool/bin/
cp: cannot create regular file `/usr/local/bin/rrdtool/bin/': No such
file or directory
a at a-desktop:~$ mkdir /usr/local/bin/rrdtool/bin
mkdir: cannot create directory `/usr/local/bin/rrdtool/bin': No such
file or directory.
