Need to install a Script-fu or Python script in Ubuntu Linux

Hello -
I need to add a layer effects plug-in to the image editing program GIMP.
Adding this will require using the terminal window in Ubuntu. I don't use the terminal enough to fully understand the instructions I've found online, so I hoped someone could break them down.
Here's some background about the issue:
The layer effects are available in python and script-fu versions. GIMP can accommodate either, although I'd rather use the python version.
I've found both plug-ins online and neither seems to be a "package" that I can follow instructions and apply. Instead both look like a list of code.
The information I've found about installing either version refers to putting it in the correct Ubuntu Linux folder, which seems to require opening a terminal and using the correct commands. I've found a Ubuntu user help page with instructions but I think they're generalized and that I'd need to know more than I do to insure they work for my computer.
So that's the help I need. I've included links to the wiki page I mentioned, and the page from the Ubuntu user help site about installing python libraries.

Thank you for any help you can give.

would be nice to post what did you really try, what is that plugin exactly.

I tried attaching the files but they're not a format this website will allow.

I have opened the script-fu file and python file and tried copying and pasting them into this document but each file had too many characters.
The files are called layerfx.scm and layerfx.py

Those instructions seem fairly complete...where did you run into trouble and/or what did you not understand?

I've tried to install the python script using the commands suggested on the wiki page I cited above. The python script is located in my downloads folder. Seemingly, the path to the file is /home/gil/downloads/layerfx.py. I've used that path in the command suggested by the wiki page in my terminal window and keep getting this result - cp: cannot stat '/home/gil/downloads/layerfx.py': No such file or directory. I've tried different variations of the path to my layer fx script and get the same message. (I've pasted my attempts from the terminal window below).

gil@gil-ThinkPad-T400:~$ sudo cp /home/gil/downloads/layerfx.py /app/lib/gimp/2.0/plug-ins
[sudo] password for gil:

gil@gil-ThinkPad-T400:~$ sudo cp /home/gil/downloads/gimp-script.py /app/lib/gimp/2.0/plug-ins
cp: cannot stat '/home/gil/downloads/gimp-script.py': No such file or directory

first you need to find that file, because currently it is not found. Where did you put it?

Moved: This thread is more suitable in <Ubuntu> and has been moved accordingly to help your thread/question get the exposure it deserves.

try /usr/lib/gimp/2.0/plug-ins/

If the commands you are posting were copied/pasted from the terminal then try changing 'downloads' to 'Downloads' due to case sensitivity.
Running: ls /home/gil, do you see a Downloads directory?

I'm running Ubuntu 16.04. In response to this Q I installed gimp, it's version 2.8.
The place I would put personal plug-ins is in ~/.gimp-2.8/plug-ins/ (where ~ is like /home/gil).
Try `ls ~/.gimp-2.8/'
