That would be because in your example, PS1 is only being affected when you
actually do a 'cd'
In my case, (and I think that of the original poster), PS1 is being
specified in the main body of my bash/ksh rc file, in which case it is
evaluated every time you do any/every command.
Your example is certainly more efficient, in that your the PATH information
is only updated when your current directory is likely to have changed, but I
actually echo every command's $? onto my prompt. i.e my prompt looks like:
RC(1) azimuth:.../last_2/path_components$
Actually, I had to create a function to do this, so that $? was properly
returned.
function _cd {
typeset saverc=$?
typeset _path=`echo $PWD | sed
'/\/.*\/.*\//{s%.*/\(.*/.*\)%.../\1%;}' `
echo "RC($saverc) $HOST:$_path\$ "
return $saverc
}
PS1='`_cd`'
Otherwise if you are simply setting PS1 with backticks in the main() of your
rc file, then your $? is hosed.
At least as far as I've experienced....
Thanks

I don't find that to be true with pdksh - PD KSH v5.2.14 99/07/13.2

Also be aware that when using backticks in your PS1 variable, you are
influencing $? as a result.
What happens, is that when you run a command (i.e. "rm
<some_file_that_doesnt_exist>") and then say "echo $?", you are getting
the
return code ($?) of your PS1 execution (which is likely to always be 0) -
NOT the $? of the "rm" command.
