    fun with homework...shell commands! (IE PLEASE HELP)

    we are working with shell scripts, in particular a reworking of setpath...

    I need to change this:

    if [ -z $PATH ]; then
    PATH=$newpath
    elif [ $PATH="." ] || [ $PATH = ".." ]; then
    PATH=$newpath:.
    elif [ $PATH=":" ]; then
    PATH=$newpath:
    elif [ ${PATH:${#PATH}-2} = ":." ]; then
    PATH={PATH/%":."/:$newpath:.}
    elif [ ${PATH:${#PATH}-1} = ":" ]; then
    PATH=${PATH/%":"/:newpath:.}
    else
    PATH=$PATH:$newpath
    fi

    into a loop....

    can anyone help???

                      Sure, sounds cool. And is it that you have a heavy social schedule or you're just disorganised?

                              Yeah, those are the 3 weeks I'm looking forward to. My bf's arranging a trip for us to Munich to interrupt it though. How selfish of him
