As a challenge to myself, I decided to rewrite this PWD function using only Bash built-ins after learning of parameter substitution. It actually does work! Here's the resulting code, if you're interested: <code> function PWD { tmp=${PWD%/*/*}; [ ${#tmp} -gt 0 -a "$tmp" != "$PWD" ] && echo ${PWD:${#tmp}+1} || echo $PWD; } </code> Cool trick!

set prompt = "%c2 # "

or

set ellipsis = 1
set prompt = "%c02 # "
