dr_peper,

I usually prefer to stick to scripting capabilities of the shell I am living in. Makes it more portable. So, I liked your solution using csh scripting. I just extended it to work on per dir in the localdirs to make it work for myself.

foreach dir ( $localdirs )
    echo ${path} | egrep -i "$dir" >& /dev/null
    if ($status != 0) then
        set path = ( $dir $path )
    endif
end
