Hamish,
why does the test refer to .alias? As I wrote in the attached mail the 
bash-alias-file should be .bash_aliases

And what I don't understand either, not even if in the .grass.bashrc is 
defined

if [ -f ~/.bash_aliases ]; then
     . ~/.bash_aliases
fi

the aliases work in grass.

... oh now I understand, do I? Do I have to change this entry in

if [ -f $USERHOME/.bash_aliases ]; then
     . $USERHOME/.bash_aliases
fi

???

No... does not work ;o(

I have this solution to change the Init.sh (see below). But it isn't a 
good one. I hope for a better one with only one alias-definition-file.

Greets to the other side of the globe
cheers
Philipp
