I'd suggest to put the change in ~/.grass.bashrc instead.


fwiw here's what I have there wrt the prompt:

SHORT_VER=`echo "$GRASS_VERSION" | cut -f1,2 -d. | sed -e 's/\.//'`
export PS1='G$SHORT_VER:\W > '
export HISTSIZE=3000

.or.

export PS1='G$SHORT_VER:\w > '
export PROMPT_DIRTRIM=2

as full dir path gets much too long, especially on WinGrass where the
terminal width is a pain to resize.


For simplicity one of my favourites is still just:

export PS1='GRASS$SHORT_VER> '


If you do most of your work with a small set of locations, it might
also be an idea to figure something out with Xresources to color the
terminal background based on which one you're running in.
