Let me explain how Gimp administers brushes,scripts and plug-ins.
Gimp comes with a "standard" set of brushes which are installed in /usr/share/gimp/2.0/brushes.
Scripts that come with Gimp are in /usr/share/gimp/2.0/scripts.
Default plug-ins are located in /usr/lib/gimp/2.0/plug-ins.
This set will always be loaded when Gimp is started.
Gimp allows you to use your own brushes,scripts and plug-ins.
To keep things neat these are
usually installed in your /home/username/,gimp-2.x/ directory.
Paths: a path directive tells a program where to find something.
This may be another program or other things to make it work correctly.
Paths are part and parcel of
any Operating System,be it Linux,Windows,Mac you name it.
Remember computers are very stupid: You have to tell them exactly what to do,a typo will make it fail.
Now to get back to your last post:
gimpPath what you have there would be correct for Windows,Linux won't understand it.
It should read:
/home/molly/gimp-2.8/brushes
This is the default brush directory and
gurm needs it to place the selected brushes.
userPath should point to where your brush collection is located.
/home/molly/gimp-2.8/mybrushes
Now you may want to call mybrushes something else,if you do then enter the correct name instead.
extensions is ok.
installedOptions should be empty since you haven't yet selected anything with gurm.
As you can see on one of my screenshots I have quite a few directories with brushes in /mybrushes.
These will show up in gurm when you run it,you can then tick what you need.
This way you'll avoid having an enormous amount of brushes in Gimp.
When you're going to do something else in Gimp you can untick brushes not needed and replace them with others.
Note: gurm is rather slow,so be patient when you change something.
