Thanks - I did try recursively grepping etc and didn't find anything.
I will try the bash 'init' check, but I don't think it can be there as wouldn't 
that imply that the BASH_FUNC__ vars would be there from the outset? And, the 
BASH_FUNCs appear at random (obviously not random, as they must be being 
triggered by something) points during the day - I can go hours and not see 
these appear - I can use sudo and rcs to do various things and they don't 

Can I ask - is there a chance that it's something that I've done in a script? 
Is there a setting somewhere that tells bash to export certain functions to the 
shell or do you have to explicitly export them to see them in the environment 
like this?
