Works like a charm - with a few minor modifications.  First, you
can put that in the chpwd function to have the code executed only
when the working directory changes.  Second, the slash before the
asterisk in the case value prevents that it works on the top
directory itself since PWD does not have the trailing slash for
directories.  I now use this script:

  chpwd ()
  {
    case "$PWD" in
      /net/server/share/home*)
        cd '/net/server/share' ''
        ;;
      /net/server/share/common*)
        cd '/net/server/share' ''
        ;;
      *)
        ;;
    esac
  }

Where "common" is a named directory pointing to
/net/server/share/common and /home is a symbolic link.


Bye
