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 theĀ 

$ 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I have no experience with RTAI but the wiki page, like most things on the wiki, is likely outdated. I would try the install instructions on the github repo:

github.com/NTULINUX/RTAI/blob/master/README.INSTALL

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.

can you post the _exact_ command you typed before you got the '>'?

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?

Not sure how that gave you the '>' prompt but:
/path/to/this/RTAI-git-tree/...

I would think that you need to replace this with the path to your local clone of the git tree from this earlier command:
$ git clone https://github.com/NTULINUX/RTAI.git

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.

Any reason for not using the ready made debs from the releases page?
github.com/NTULINUX/RTAI/releases
Or from here
linuxcnc.org/dists/bookworm/base/binary-amd64/
and the corresponding LinuxCNC build from here
linuxcnc.org/dists/bookworm/2.9-rt/binary-amd64/
