Cannot stat/ no such file or directory

wiki.linuxcnc.org/cgi-bin/wiki.pl?Building_RTAI_5.2_Packages
this is the wiki I am using to install RTAI and i am getting stuck on the "2.) Patch kernel with IPIPE, in this case we use 4.14.148". Specifically the 

$ sudo cp -aLv /path/to/this/RTAI-git-tree/ksrc/patches/v4.14.148/*.patch /usr/src/

(I am doing this in root)is giving me

cp: cannot stat 'path/to/this/RTAI-git-tree/ksrc/patches/v4.14.148/*.patch': No such file or directory

Im not new to linux, but definitely don't know enough about linux commands.

I got through most of the first part but got stuck on "for i in". The new line after would just show ">" and did not know how to get out, so I closed terminal, and now I don't know how to continue from here.

for i in "/path/to/this/RTAI-git-tree/ksrc/patches/v5.4.279/"*.patch ; do patch -p1 < "${i}" ; done
I verified I had this correct before I sent it in the command line. Just in case I missed something, I'll try it one more time. Do I just have to repeat that one command?

To be honest I'm still not sure what to do.

This wouldn't happen to be what you are saying is it?

$ git clone /ksrc/patches/v5.4.279/"*.patch ; do patch -p1 < "${i}" ; done

I think I'm going to send it, because I found in the /usr/src/RTAI/ksrc/5.4.279 there are 4 .patch files that I think are what I needed.
