    Confused by PS1 in Solaris 9

      For years I have had the current working path in my PS1 prompt on many different systems -- AIX, Solaris and Linux.
      I am at a new place and am trying to set this up again, but I can't seem to get it to work so that when I change directories, the new location is reflected in the prompt.
      I am noticing that when I issue "set" PS1 is displayed as PS1='host:path'. That is, there are single quotes around the resolved $(hostname):$(pwd) values.

      If the above is not clear

      I put into my .profile


      After saving .profile, I enter the command

      . ./.profile

      The prompt looks right.
      then I enter


      and what is displayed for PS1 is


      if I then change the directory

      cd ..

      the prompt does not change.
      I want the prompt to change.

      Hopefully this is clear enough.

      So, what am I not remembering, and thus doing wrong.

          You're probably using bash syntax and your shell on Solaris is not bash.

          Change your shell to bash.

            bash has nothing to do with it, this is Solaris and Korne shell.

            Finally found the answer ==> PS1="\$PWD"
            That is the basic form to get the current working directory into the prompt so that it will change/update whenever you enter the cd command.

            You must use double quotes.
            You must quote the $ with a back-slash
            You must use the PWD variable, not the pwd command -- note the case.
            use of braces is optional ==> PS1="\${PWD}"

            I though I remembered being able to use $(pwd), but I must have been wrong -- misremembered.

            So, what I have in my .profile is

            tty -s
            if [ $? -eq 0 ]
            export PAGER=less
            export EDITOR=vi

            this produces a prompt like:




            that way, when I change the directory to some long path, I still get to know where I am, and not obscure the next command I enter; e.g.

            $cd /usr/adm/best1_default/bgs/monitor/log


            Hope this helps someone
