1.To set your prompt in rc to reflect your current directory add this to your profile.
a.fn cd { builtin cd $* && prompt=(`{pwd}^% '' ) }

a.prompt = (`{cat /dev/user}^@^`{cat /dev/sysname}^'% ' ' ')
a.fn `{echo $prompt(1) | tr -d ' '} { $* }
3.A Plan 9 Boot Camp user contributed prompt.
a.prompt=('['^`{pwd}^'] '^$sysname^'% ' ' ')
b.fn cd {builtin cd $* && prompt=('['^`{pwd}^'] '^$sysname^'% ' ' ')}
